Laser line filters are ideal for transmitting laser light while suppressing ambient light. The center wavelength shifts linearly with temperature less than 0.02 nm/°C. The highly reflective side of the filter should generally face the source, minimizing the thermal load on the blocking glass and epoxies. These filters are on clearance and only available for a limited time while supplies last.

Features
Excellent Out-of-Band Blocking
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.
Center Wavelengths for Common Lasers
Wavelengths range from the ultraviolet to the near infrared, covering most of the common laser lines. 12.7 and 25.4 mm diameter filters are available in most wavelengths. They are mounted in a black anodized aluminum housing to protect the filter from humidity and handling.
Sensitivity to Angle of Incidence
An increase in the angle of incidence causes a shift of the center wavelength to shorter wavelengths. This can be very useful in tuning a narrowband filter to a desired wavelength. The wavelength shift with angle of incidence, can be calculated by: λθ= λo [1-(no/ne)2 sin2θ]1/2 where λθ is the wavelength at the new angle of incidence; λo is the center wavelength; no is the index of refraction of the environment (no = 1 in air); ne is the effective index of refraction of the filter; and θ is the angle of incidence.
Excellent Temperature Stability
The center wavelength shifts linearly with temperature less than 0.02 nm/°C. The wavelength shifts in the direction of the temperature change. In use, the highly reflective side of the filter should generally face the source, minimizing the thermal load on the blocking glass and epoxies.
