Where to Buy Interference Filters

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

Knight Optical have a vast range of mounted interference bandpass filters available from our stock catalogue. We have narrow, standard and broadband options with wavelengths centred in the UV, visible and NIR regions. We offer specific ANPR filters with NIR centre wavelengths which correspond to commonly used LED wavelengths (740 nm, 850 nm, 870 nm and 940 nm). We also offer fluorescence filter sets which include excitation and emission interference bandpass filters which work with common fluorophores. As well as our large stock range, we also offer custom interference filters to suit your application.

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.

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.

Vortex supply a wide range of bandpass and edge filters for visible and IR applications. We have inhouse design and manufacture using state of the art deposition equipment. Common applications are gas detection, industrial process monitoring, medical applications, smart agriculture and machine vision.
