LCTF-N20 Liquid Crystal Tunable Filter

Scanning Accuracy: 1 nm Maximum Polarization Transmittance: ≥40% Out-of-Band Rejection: ≥OD3

The Liquid Crystal Tunable Filter (LCTF) independently developed by Zhongda is a spectroscopic device based on dynamic wavelength selection technology based on the optical properties of liquid crystal. It can quickly adjust the wavelength of transmitted light through electronic control to achieve spectral splitting functions. This product can be connected to a computer through a USB interface, and the required wavelength and other parameters can be input on the supporting software operation interface to achieve flexible narrow-band filtering of incident light. In addition, it has adaptive temperature compensation capabilities. The calibration database can also be used to correct spectral drift caused by changes in field of view angle to meet the needs of larger field of view imaging. It can be combined with imaging lenses and image sensors (CMOS/InGaAs, etc. ) to form a compact hyperspectral imaging system. Therefore, this product is mainly used in scientific research, supplemented by other industries, to help photoelectric imaging equipment achieve intelligent spectroscopy

The fibre-optic Prague raster (FBGs) is a widely used key photoscope. Alignable fibre-optic flask instruments provide a trombone platform; provide a “full fibre-optic” advantage; and are widely used in fibre-optic communication systems, tradable lasers and fibre-optic sensors. The fibre-optic rasters are based on our innovative proprietary harmonization techniques; they use pure compression to adjust to adjust to achieve a wavelength range. The fibre-optic raster is designed to reconcile wavelengths of different types of fibre-optic rasters; including; fibre-optic Prague rasters; transport fibre-optic rasters; or long-cycle fibre-optic rasters. Full fibre-optic filtration filters, pure axle compressions to achieve a large wavelength range, capable of reconciling different types of fibre-optic rasters with high power
