Where to Buy Interference Filters

Optometrics, a Dynasil company, carries a large inventory of bandpass filters for a variety of wavelengths. These interference filters find applications in spectral analysis, particularly those in clinical chemistry, spectral radiometry, environmental testing, laser line separation, flame photometry and color separation where the required wavelengths are well known. Custom bandpass filters are offered to instrument manufacturers worldwide. Please request a quote.

LASEROPTIK can design and fabricate a wide range of interference filters for standard and special applications.

Artifex Engineering offers custom interference filters for use in the UV, VIS and IR. Bandpass filters, notch filters, highpass or lowpass filters are available and can be cut to any shape. To reduce the number of layers, absorption filters (color filters) can be combined with a dielectric coating. Black anodized aluminium rings may be provided for ease of mounting. Visit our product page for more information. We look forward to your inquiry.

VisiMax process color filters selectively and accurately pass light of a small range of colors while reflecting other colors. Our heat-resistant dichroic filter coating technology produces durable interference filters that render light with precise spectral control.

Accelerate your project by choosing a standard VisiMax color filter, or utilize the expertise of our skilled design team to create a custom filter to meet your specific spectral requirements.
