1.This is a night vision product for dark night or weak light condition observation.It provides 5X optical magnification and 8X digital magnification.

2.This product is the best auxiliary tool for human vision extension.In weak light environment, the observation distance is infinite. In dark, it can reach up to 200 meters.The eyes of beast glare perfectly even at a great distance. A small bird was found 100 meters in the eyes.

3.The filter cap makes this monocular suitable for daytime and nighttime observing.The filter neutralizes the infrared color, so cover the filter for daytime viewing and uncover the filter for the nighttime viewing to get better experiences.

4.The device is powered by 3*AA NiMH Battery which are easy to get in the local store. And the battery status shows on the display so that easy to notice when the batteries are running out. Batteries are not included.

5.Infrared lamp power upgraded from 1W to 2W, and the illumination infrared wavelength is adjusted to 850. The power is greater, the wavelength is shorter and the light is stronger, images are clearer. Brightness is nine-level adjustable.

Convenient hybrid adapter lets you use older style M42 format eyepieces in modern telescopes that typically only accept 1.25" format eyepieces.

•  This flexible, articulate probe can navigate through tight spaces with ease. It bends and rotates, allowing access to even the most challenging areas, all while maintaining crystal-clear visibility. 

• Powered by a large-capacity Li-ion battery, Huepar laser measure offers remarkable run time for all-day jobs and can work up to 8000 times when fully charged. 

Optical condensers are optical components used to concentrate and direct light beams in microscopy or other imaging systems. They consist of a lens system that collects diverging light rays from a source and focuses them into a parallel or converging beam. These condensers are typically utilized to enhance the illumination and resolution of samples by providing uniform and intense lighting. The type 2 condenser is fixed to the bottom of the working stage with 3 screws. It requires 3 mounting hole at the bottom of the stage, and the working stage must be metal. Screws are included.
