OD2 - OD4 Long pass Optical Filters LP650 Optical High Transmittance
Longpass filters are designed to have a sharp transition at each cuton point. This line can be used for making bandpass filters when you combine with our shortpass filters. Substrate material is fused silica which has high durability against heat and high transmittance.
Advantages:
1) High Transmission,and the optical signal attenuation rate is small, effectively improve the working distance and light intensity;
2) High cut-off rate,effectively prevent stray light interference;
3) High wavelength accuracy
4) More than 10 years’ experience in the production of optical filter, imported coating equipment to produce, IAD ion assisted deposition technology and to ensure that the low temperature drift and film firmness stronger
