An optical bandpass filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These optical bandpass filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums.
- UV, VIS, IR Ranges
- Circular and Square Sizes Available
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 and order sorting applications.
Neutral Density (ND) Filters
ND Filters, also known as Neutral Density Filters, are often used in imaging or laser applications where excessive light can be damaging to camera sensors or other optical components. ND Filters are also ideal for preventing excessive light from causing inaccurate results in photometer applications.
Shortpass Edge Filters
Shortpass Edge Filters are used to transmit wavelengths shorter than the cut-off wavelength of the filter. Shortpass Edge Filters are commonly use in life science applications including fluorescence microscopy or for integration into a variety of instrumentation.
Imaging Filters are Optical Filters designed to improve the image quality in imaging or other machine vision applications. Imaging Filters are often offered mounted to ease integration onto Imaging Lenses
