Narrow Bandpass Filter

Yunlang can provide precision filters for many applications, including bandpass interference filter (band pass filters), Cut off filters, UV bandpass filter, Narrow bandpass filter, ND filter, Negative Filter or Notch filters, dichroic, color substrate.

Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries.

Custom filters are available for both large manufacturing needs and in prototype volumes. Contact us for more information or to arrange a quote.
