Technical Data
Thin-film linear polarizer, 400–700 nm, ring-mountable
● Operating wavelength: 400–700 nm
● Mechanical housing dimensions: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm
● Suitable for low-power applications, with a high extinction ratio and a large incident angle.
● The housing is engraved with the product model number and an alignment mark indicating the vibration axis direction, for ease of use.
The air‑side surfaces of the substrates on both sides of the thin‑film linear polarizer, which operates at wavelengths of 400–700 nm, are coated with anti‑reflection films tailored to this spectral range. The device is mounted in mechanical retaining rings with diameters of Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm, offering clear apertures of Ø10 mm, Ø21.5 mm, and Ø45 mm, respectively. This thin‑film linear polarizer is well suited for low‑power applications and, when used to generate linearly polarized light, delivers a high extinction ratio and an acceptance angle of ±20°. All three models feature the product model number and the polarization axis orientation engraved on the housing, ensuring ease of use. Note: Due to the transition between old and new product generations, the engraving on the housing may not always match the product model number; however, this does not affect performance, so please use with confidence.
Thin-film linear polarizer, 700–1700 nm, ring-mountable
● Operating wavelength: 700–1700 nm
● Mechanical housing dimensions: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm
● Suitable for low-power applications, with a high extinction ratio and a large incident angle.
● The housing is engraved with the product model number and an alignment mark indicating the vibration axis direction, for ease of use.
The air‑side surfaces of the substrates on both sides of the thin‑film linear polarizer, which operates at wavelengths from 700 to 1700 nm, are coated with anti‑reflection films tailored to the respective spectral range. The device is mounted in mechanical retaining rings with diameters of Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm, offering clear apertures of Ø10 mm, Ø21.5 mm, and Ø45 mm, respectively.

Square thin-film polarizer, 400–700 nm, unassembled
● Dimensions: 50×50 mm or 100×100 mm
● Wavelength range: 400–700 nm
● The incident angle range is ±20°.
Chongfan Technology’s square thin-film polarizers are available in two models: FLP‑VIS‑50 and FLP‑VIS‑100, with dimensions of 50 × 50 mm or 100 × 100 mm, respectively, and a operating wavelength range of 400–700 nm. Both sides of the thin-film polarizer are coated with protective films, which bear markings indicating the polarization axis; these protective layers can be removed as needed during use. The polarizers transmit and absorb polarized light within a specified wavelength range, making them well suited for low‑power applications while delivering an exceptionally high extinction ratio.
