About this product
Broadband green film ensures light transmittance and filtration, while low reflectivity increases light transmittance and ensures clear vision.
The multi-layer broadband green film has strong permeability and is coated with ultra-clear multi-layer FMC broadband. The color is bright and transparent, and the edges have extinction lines, which can effectively reduce eye fatigue.
The concave and convex anti-slip design is not easy to slip. Turn the handwheel to adjust the sharpness and achieve precise focusing. The operation is simple and convenient.
Using BKA4 prism, the exit pupil has a patterned spot, high transmittance, clear and bright, large field of view, good field of view, low-light night vision, clear vision at night, and stable imaging.
Plastic frame, durable structural design, fashionable and beautiful, rubber protection around the eyepiece makes eye observation more comfortable.
