Product Description

General Introduction: Laser line filter is an ideal choice to transmit laser and suppress ambient light at the same time. The linear shift of central wavelength with temperature is less than 0.02 nm /ºC. The high reflective side of the filter should normally face the light source to minimize the heat load on the blocking glass and epoxy resin.

Products Name: Laser Line Bandpass Filters
Alias: Laser Line Bandpass Filters, Laser Line filters, Laser line optical filters, Laser optical filters, Laser filters, laser bandpass filters, etc

*****

Main Characters:
1).Out-of-band blocking to less than 0.01% (10^-4)
2).Excellent temperature stability
3).Center wavelengths at common laser lines                    
4).12.7 and 25.4 mm diameters
5).Very strong out of band shielding characteristics
Our filters have excellent out of band blocking of less than 0.01% (10^-4). The high reflective side of the filter should normally face the light source to minimize the heat load on the blocking glass and epoxy resin.
6).Central wavelength of ordinary laser
The wavelength range is from ultraviolet to near infrared, covering most common laser lines. 12.7 and 25.4 mm diameter filters can be used for most wavelengths. They are installed in a black anodized aluminum housing to protect the filters from moisture and handling damage.
7).Sensitivity to incident angle
The increase of incident angle results in the shift of center wavelength to shorter wavelength. This is very useful for tuning the narrow band filter to the desired wavelength.
8). Excellent temperature stability
The central wavelength is lower than 0.02 nm/ ° It moves linearly at C. The wavelength moves in the direction of temperature change. In use, the high reflective surface of the filter should face the light source to minimize the heat load on the blocking glass and epoxy resin.

Products Highlights:
1).Different grades materials for option.
2).High precision & high surface roughness;
3).Sizes can be customized as per the customers' request
4).Quick lead time and delivery time.
