Laser Line Filters are ideal for transmitting laser light while suppressing ambient light. Our filters have excellent out-of-band blocking, less than 0.01% or 10^-4. The center wavelength shifts linearly with temperature less than 0.02 nm/°C. The wavelength shifts in the direction of the temperature change.

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:

λ = λ_o [1-(n_o/n_e)² sin²θ]^1/2

Where λ is the wavelength at the new angle of incidence; λ_o is the center wavelength; n_o is the index of refraction of the environment (n_o = 1 in air); n_e is the effective index of refraction of the filter; and θ is the angle of incidence.

The highly reflective side of the filter should generally face the source, minimizing the thermal load on the blocking glass and epoxies. 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.
