High Quality UV Metal Coated Neutral Density (ND) Filter, Φ50mm, OD=1.3, United Optical Technology Co., Ltd (CAT#: STEM-OP-4069-YJL)

Highlights

ND filters reflect the portion of light that is not transmitted, uniformly reducing transmission in a portion of the spectrum. Reflective neutral density filters use the principle of thin film interference to transmit part of the light and reflect the other part.

Cat Number: STEM-OP-4069-YJL

Application: Commonly used in imaging or laser applications to prevent damage to camera sensors or other optical components caused by strong light.
