TwinFilm Technology

Developed by Spectrolight, an Avision partner, it combines two broadband bandpass filters in a compact, opaque housing.The angle of incidence of each filter is rotated independently of each other.It is a simple, economical and efficient method of filtering light waves.

This patented technology can be used in fluorescent microscopy, high spectral imaging, machine vision, and other applications.Excellent alternative to monochromators and AOTFs. 

of transmitted light from any collimated light sourceCenter wavelength and bandwidthAll are fully adjustable, with a third glass plate to counteract any slight deviation in the beam path.

 

 

Bandwidth can be found in the 1.5 nm and 20 nm The center wavelength can be selected to be almost any visible wavelength ((350 nm - 900 nm)The

Compared with other similar wavelength tuners, HONGKE's wavelength selector has a clear technical advantage, as shown in the figure on the right.

  • Compared with AOTF, Hongke wavelength selector has no optical axis shift during wavelength adjustment;
  • Compared with the slit exit of monochromator, the exit of HONGKE's wavelength selector is a through-hole with a diameter of up to 10mm, and the area of 95% is uniformly illuminated.

Hongke wavelength selector has more than 75% transmittance, far more than the lenticular monochromator and AOTF, etc., and the depth of stray light suppression outside the passband can reach more than OD6, fully eliminating interference.
