Laser Filter Description

Laser-Filter are used to reject a wavelength or range of wavelengths while transmitting wanted wavelengths for a number of laser applications.  Shapeoptics offers a wide range of Laser line Filters suited for many laser system needs.

Focused on the laser’s resonance, laser line coating are narrow bandpass coatings that reduce the background plasma and secondary emissions that often contribute to incorrect signals. These filters can be used to increase the monochrome of the light output when utilizing diode lasers and LEDs. Taking gas lasers as an example, these filters can eliminate plasma in the deep blue wavelength region.

 Applications

●Laser-based Fluorescence Instrumentation

Raman Spectroscope

●Analytical and Medical Laser Systems

Laser Filter Curve

 Applications Benefits

● Ultrahigh Peak Transmission T >80%

● Excellent Blocking (OD>4.0): Our laser line bandpass filters cover most of the common laser lines and feature excellent out-of-band blocking of less than 0.01% (10-4). The highly reflective side of the filter should generally face the source, minimizing the thermal load on the blocking glass and epoxies.

● Dielectric Coated with IBS Technology

Shapeoptics  has launched to make and supply optical laser coating for military applications. Laser protection coatings can block both Ruby (694nm) and YAG (1064nm) lasers deeply and transmit visible wavelengths effectively. We can arrange the filter with suitable size for binocular or coat for another kind of laser. Custom filters are available for both large manufacturing needs and in prototype volumes.
