2019-07-20 Company News 7388 次浏览
The 940nm narrowband filter is an optical component formed by a special coating process on the surface of various glass materials. It can select any desired wavelength from the incident light, and its half peak is generally between 5 and 50 nanometers. It can also replace expensive spectral devices such as gratings, widely used for various spectral measurements and generation. Chemical analysis instruments, optical experiments, and industrial fields.

Our company's 940nm narrowband filter technical parameters:

Cut off depth: OD3-OD6
Product features: Accurate wavelength positioning, high penetration, deep cut-off depth, small temperature fluctuations, good durability, good smoothness, etc.

Precautions for use:
1. Please wear gloves when using, and do not touch the surface of the lens directly with your fingers to avoid affecting the luminous effect of the lens.
Step 2. If the surface of the lens is dirty, a dust-free cloth or paper can be used to wipe the surface of the lens with alcohol.
When checking the optical path, please take appropriate protective measures. The unit price of all products published online must be determined based on the customer's requirements, order quantity, and size. Therefore, the corresponding unit price cannot be accurately determined online. We hope our customers and friends can understand!
