Filters

Tempotec fabricate many kinds of optical filters including color glass filter, neutural density filter, band pass filter, IR cut filter, IR pass filter, birefringent filter, interference filter, etc..

Longpass Filter
Longpass filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications. Available in a variety of cut-on wavelengths, these filters are designed for fluorescence,order sorting applications, and Display. Eliminate stray light by creating c...
Shortpass filters
Shortpass filters are designed to have a very sharp transition from transmission to reflection, making them extremely useful in a number of applications. Available in a variety of cut-off wavelengths, they are ideal for fluorescence applications, Display, separating spectral orders, and creating cus...
Color Glass Filter
Due to its selective absorption in visible wavelength range, color glass filter will exhibit various color depending the glass type. Color glass filter provides an economical filter for various applications, such as camera filter, machine vision lens filters, industrial measurement, environment prot...
Neutral density (ND) Filter
Neutral density (ND) filters are used to attenuate incident radiation without altering its spectral distribution. The neutral density value of an ND filter is related to the transmittance by: OD=Log10(1/T) or T=10-OD Optical Density: OD Transmittance: T Absorptive Neutral Den...
