Product Details

Optical Coated Band-pass Filters

1.Product Description

Optical coated band-pass filters are optical components designed to selectively transmit light within a specific wavelength range while blocking unwanted wavelengths.

2.Working Principle:

(1) Utilizes multilayer dielectric coatings deposited on substrates to achieve high transmission (>90%) in the target band and strong blocking (OD4+) of out-of-band light (e.g., UV, visible, or IR).

(2) Typical structure: Combines short-pass (SP) and long-pass (LP) filters to create a well-defined passband.

3. Applications：

(1) Optical detection and analytical instruments.
(2) Lasers and optical communications.
(3) Industrial and machine vision.
(4) Aerospace.
