GOKO Bscan-Z is capillaroscope that is designed and manufactured by GOKO, an innovative Japanese manufacturer specializing in optical imaging equipment since 1953. See its amazing clarity and experience the difference.
GOKO's optical innovation achieves greater clarity and higher contrast to enable the observation of flow of white corpuscles in capillaries. Even after the launch of GOKO Bscan-Z, the third model of GOKO Bscan series, we continue to work on improvement by incorporating customer feedback.
The GOKO Bscan-Z greatly reduces vibrations of fingers with the improved stage unit and anti-vibration attachment (standard accessory). It improves work efficiency of taking photographs or observing of circulation in the capillaries as well.
The GOKO Bscan-Z adopts optical zoom which provides clearer images even in ultra-high magnification. Moreover, you can easily change magnification from lower magnification (145X) to ultra-high magnification (590X) without changing lenses simply rotating the ring.
Outstanding optical design of GOKO Bscan-Z provides top-class clear image of capillaries. Blood flow is clearly observed even the movement of red cells. Even ultra-magnified images are very clear because the zoom is not digital, but optical.
Exclusive stand can be moved in all directions, X-axis direction, Y-axis direction and Z-axis direction.
The preparation time for observation has been greatly shortened, and work efficiency has been greatly improved.
Furthermore, improvements have been made so that users with long nails can observe their nailfold capillaries without damaging the long nails.
The robustness of the stand is a very important factor during ultra-magnification observation.
The compact and portable camera unit of the GOKO Bscan-Z is only 150 g, which enables single-handed operation for long periods of time without stress.
It also solves problems such as "capillaries at the observation site are pushed by the weight of the camera and blood flow stops."

Manual focus. Because the depth position of the capillaries differs from one to another, it would be quite difficult for the auto-focus camera to focus well on the exact point you want to observe specially at ultra-high magnification. GOKO Bscan-Z enables quick and accurate focus on any visible skin capillaries. In addition, very clear capillary images can be obtained since the zooming is performed optically instead of digitally. These optical designs enable clear observation of leukocyte movement even at very high magnification.
GOKO Bscan-Z is mainly designed to be projected on a dedicated 9.7" monitor for easy observation. However, still images and uncompressed movies can be saved by using the optional NTSC-USB2.0 converter set.
Using the 2D measurement software included with the converter, you can measure the distance between two points and the length of a curve using multiline.We also have "GOKO-VIP" software that can quantify the flow velocity using moving images of capillaries.
We also offer "GOKO Measure Plus", a high performance image processing software.
You could observe not only nailfolds, but also every body parts. By removing the camera from the stand, you could observe all parts of the whole-body surface such as the arm, the scalp, the legs, the tongue, the gums, and so on. In those cases, please use the optional Non-reflection cap set to obtain a clearer image without any reflection.
Optional Autoclavable non-reflex cap is available for use in clean fields.
The camera weighs 140g, which is very light. The size of the camera is as small as 96mm, so there is no burden even if it is used for a long time.
With the optional Camera handgrip, you can get a very stable image when observing capillaries.
No periodic maintenance is required. The camera uses LEDs as its light source, and in principle, there is no need to replace the lighting.
Oil and gel is essential for the observation. Contact us for details.
The body parts where the skin is relatively thin, such as fingertips, can be easily observed. On the other hand, the body part whose keratinous are thick, such as heels, might be difficult to be observed.
The Anti-vibration cap and the stand unit are GOKO's anti-vibration design. They gently secure the fingers and greatly reduces the tremors of fingers without stopping the movement of capillaries. They are standard accessories.
Non-reflection cap is an optional cap that enables capillary observation without any reflection in the capillary images. It was uniquely designed by GOKO. It is to be mounted in the tip of the camera body.
No. Since it is not a medical device, anyone can use it without qualifications.
Yes. Frontal, parietal, and occipital areas can all be observed. Clear and non-reflective movie can be obtained by using the optional Non-reflex cap set and Camera handgrip. If you observe a scalp with a lot of hair, use a smaller caliber cap (5φ) from the cap set.
Yes. Use the Autoclavable non-reflex cap. Apply transparent toothpaste to the glass surface of the non-reflection cap to observe capillaries in the anterior gingiva, mucosa, and tongue. If you use regular Non-reflex cap, not autoclavable one, use a food-grade plastic wrap film to cover the cap after applying transparent toothpaste to the glass to keep cleaness. We recommend the use of rubber bands to prevent wrinkles in the plastic wrap.
Yes. When using a stand unit, the low magnification is 145x and the high magnification is 590x. The magnification can be easily changed with the zoom ring.
At lower magnification (145x), it is possible to grasp the shape and density of capillaries and it is easy to determine which point to be enlarged to 590x.
At higher magnification(590x), it is possible to see how the white capsules move and to observe velocity easily and clearly.
(Note) Magnification is converted on 20-inch monitors, so it is to be even larger on monitors larger than 20-inch.
Oil or gel is essential for the observation of the capillaries just below the dermis of the skin. Contact us for further clarification.
When you use the camera with the stand unit, you can avoid partial reflections by bending the tip of your finger slightly downward. When you use the camera as a handheld camera, please use the optional Anti-reflection cap set.
Yes. You can easily observe skin texture as well by using the attached focus cap without applying oil or gel. The GOKO Bscan-Z is also widely used for the research on the relation between skin texture and skin capillaries.
You can use the free software "IC Measure" which is included in the optional NTSC-USB2.0 Converter Set, or the optional measurement software "GOKO Measure Plus". Accurate values can be obtained by calibrating with the chart first.
Generally, the ring finger of the non-dominant hand is recommended to be observed. It is said that the nailfold skin of the ring finger of the non-dominant hand is the thinnest and thus the capillaries there are easy to be observed. However, choose another finger depending on individual conditions. In some protocols, it is recommended to observe eight fingers except the thumbs.
Yes. We accept customization from one unit. Feel free to contact us if you have any special requests such as observing at higher magnification, changing the shape of the scope, or increasing numbers of pixels.
In the medical field, our device is widely known by the terms "capillaroscopy" and "Nailfold Video Capillaroscopy (NVC)," and is used in a wide range of fields, including internal medicine, plastic surgery, orthopedics, dermatology, emergency centers, and rehabilitation departments at university medical schools, affiliated hospitals, and public and private hospitals, as well as pharmacy departments and pharmaceutical companies.
In the field of health, it is widely used in acupuncture and moxibustion clinics, fitness clubs, health food manufacturers, health appliances, functional water, hydrogen, etc. to confirm the effects of treatments and equipment.
In the beauty field, the system is used to visualize the effects of cosmetics manufacturers, esthetic salons, and beauty clinics.
It refers to the blood circulation in microvasculature, i.e., micro-arteries, capillaries, micro-veins, and arteriovenous anastomoses. Although not all the microcirculation can be observed, the GOKO Bscan series enables us to estimate the body functions and health conditions by observing the microcirculation in every part of the skin surface.
Yes. Use the optional Non-reflex cap and Camera handgrip. Apply gel or oil to the glass surface for observation, and you can obtain clear, non-reflective video of blemishes and skin capillaries. Both skin spots, melanin and capillaries can be observed clearly.
See: https://youtu.be/UVhmB-wBYKg and https://youtu.be/9YUYvgBwkCM
The mechanism of skin blemishes (an example of senile pigmentation) is due to an imbalance in the production and discharge of melanin in the skin caused by a disturbance in the skin turnover, which is a cyclical function in which new cells produced in the lower part of the epidermis reach the stratum corneum at the top surface and are peeled off as plaque, resulting in an abnormal accumulation of melanin in the epidermis. This is due to the abnormal accumulation of melanin in the epidermis. It is said that where there are many capillaries, factors that stimulate the production of melanin are produced, which activates the spots.
