590× Ultra-High Magnification
― In One Hand

Expand what you can observe, and where you can observe it.
Traditional ultra-high magnification imaging required fixing the device to a stand due to extreme sensitivity to hand movement and a shallow depth of field.
The GOKO EV-13 breaks that barrier, delivering stable, ultra-high magnification observation ― completely handheld.

Experience 590x magnification with one hand ― something once thought impossible.

Deep depth of field in ultra-high 590x magnification

In ultra-high magnification observation, depth of field is often shallow, which can cause frustration because it is not easy to focus on the subject.
In addition, depth of field was not so much required for traditional observation of flat subjects such as prepared slides.

The GOKO EV-13 has achieved a "deep depth of field" by focusing on "one-handed observation" despite its "ultra-high magnification".

GOKO's unique "non-slip" tip mechanism

Revolutionizing handheld ultra-high magnification.

Why does GOKO's unique tip mechanism matter?
Explore its three powerful benefits below.

The non-slip tip mechanism advantage

Effortless fine focus

At high magnification, even subtle finger movement can blur the image. The EV-13 solves this with a touch-based focusing system ― just gently press or pull the tip to find the perfect focal plane.

Reduced slippage, minimal damage

With a field of view under 1 mm, maintaining position is critical. The non-slip tip helps you stay on target ― without harming the subject.

Build to last, easy to replace

The tip seal is oil-and alcohol-resistant, and replaceable. 50 seals included as standard, with additional packs available.

Optimized Grip for One-Handed Operation

The design makes it easy to hold stably with one hand and to turn the focusing ring with the same hand.

Win / Mac / iPad (Type-C) / Android compatible.

Can be connected to an iPad.

With the support of UVC in iPad OS17, you can now connect GOKO microscopes to your Type-C equipped iPad to observe and save clear real-time images. A USB conversion adapter to USB Type-C is required. Output to Windows, Mac, and Android devices is also supported. Please contact us for information on compatible software.

Note: Due to device specifications, some models may rarely be unsupported.

Portable with Dedicated Semi-Hard Case

The EV-13 comes in a durable, easy-to-carry semi-hard case (250 × 155 × 80 mm), perfect for mobile professionals.
