Anti-vibration design!
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.
Optical zoom provides clear images. No need to change lenses!
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.
Traditional capillaroscope GOKO Bscan-Z
Gives sharper and clearer images of even red capsules.
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.
Y-axis movement NEW! X-axis movement
The usability of the exclusive stand has been greatly improved!
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.
X-axis movement - moving the finger table to the left and right
Y-axis movement - moving the finger table back and forth
Z-axis movement - moving the camera up and down
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.
Extremely light and compact!
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."
Using the conventional focus cap (560X) Using the Non-reflex cap (560X)
Make the whole-body capillary observation "Non-reflex"!
Optional Non-reflex cap realizes non-reflection capillary observation. It does not press capillaries: Natural flow of blood can be observed. Learn more on the Option page. Autovlavable cap is also available.

FAQ
Q. It seems to be in focus immediately, is it auto focus?
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.
Q. Is all we can do with the GOKO Bscan-Z is to observe capillaries?
No. By using the software "GOKO-VIP", you could quantify the velocity. By using the optional NTSC-USB 2.0 converter Set, you could save still images and uncompressed videos. The distance between two points can be measured using free measurement software attached to the converter set.
Q. Can I observe only nailfolds?
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.
Q. Is the camera heavy? I want to use the camera by hand.
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.
Q. Does the device require regular maintenance?
No regular maintenance is required.
Q. Do I need any consumables to observe capillaries?
Oil and gel is essential for the observation. Contact us for details.
Q. Are there any body parts where capillaries are easy to be observed? Are there any body parts where capillaries are hard to be observed?
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.
Q. My fingers tremble easily. Isn't it difficult to observe the nailfold capillaries due to camera shake?
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.
Q. Do I need a special license to use the GOKO Bscan-Z?
No. Since it is not a medical device, anyone can use it without qualifications.
Q. Is it possible to see the capillaries on the scalp?
Yes. You could observe any parts of the scalp: the frontal, parietal, and occipital parts. Clear and non-reflective movie can be obtained by using the optional Non-reflection cap set. If you observe a scalp with a lot of hair, use a smaller caliber cap (5φ) from the cap set.
Q. Is it possible to observe the capillaries even in the oral cavity?
Yes. By applying gel to the glass surface of the anti-reflective cap and covering it with a wrap film, capillaries of the anterior gingiva, mucous membrane, and tongue can be observed. We recommend using rubber bands to prevent wrinkling of the wrap.
Q. Does the GOKO Bscan-Z focus at two magnification: lower and higher magnification?
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.
Q. What is the effect of oil?
Oil or gel is essential for the observation of the capillaries just below the dermis of the skin. Contact us for further clarification.
Q. What should I do when I found partial reflection in observing nailfold capillaries?
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.
Q. Is it possible to observe skin texture?
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.
Q. Is it possible to measure the size of capillaries?
Yes. You could measure the size with the free software "IC Measure" included with the optional NTSC-USB2.0 converter set. It is possible to obtain accurate values by calibrating the chart first.
Q. Which finger is commonly used to observe nailfold capillaries?
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.
Q. Is it possible to observe at another magnification that is different from the standard specification?
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.
