Advanced Functions

Improving image resolution: High-resolution HDR

A high-resolution image is obtained by using short-wavelength light and the HDR (High Dynamic Range) function to capture multiple images at varying shutter speeds. This produces a high colour gradation image with high resolution and sharp contrast that was previously impossible to obtain.

Pixel shift technology

Short-wavelength filter achieves higher resolution

The optimal wavelength of light is selected based on the characteristics of the lens to capture sharp images with minimal chromatic aberration. By combining short wavelength light with KEYENCE's original pixel shift technology, image resolution can be increased by up to 25%.

HDR+ function

The camera captures multiple images at different brightness levels by varying the shutter speed, and then produces an image with a high level of colour gradation data. This allows for clear observation of targets with glare or low contrast that would be impossible to image accurately with traditional microscopes. A new algorithm that accurately represents the colours of the target makes observation more similar to that with the naked eye.


❚The narrow range of brightness levels causes glare in areas that are oversaturated.
❚Subtle changes in contrast cannot be visualised because of coarse colour resolution.
❚Colours differ between what the human eye sees and the captured image.


❚A wider range of brightness levels diminishes the perceived glare.
❚Enhances low contrast areas for improved detail.
❚Natural colours are accurately reproduced.
