Barium fluoride (BaF2) has neary 90% transmittance in the wavelength of 200-9500 nm. lt has a widest broadband opticaltransmitance and can transmit from far ultraviolet to long wave infrared, therefore it can be used in various applications, suchas infrared spectroscope. The low refractive index of barium fluoride is 1 .48, which can provide high transmitance withouianti reflection film, in a dry environment, calcium fluoride windows can endure up to 800 dearees of ambient temperature, buiexposure to water for a long time will reduce the transmittance in the range of vacuum ultraviolet light. However, comparedto the calcium fluoride window, the resistance of the barium fluoride window to the moisture is lower, and the BaF2 windowis the most resistant to high energy radiation, but it has a lower transmission of Uv. The knoop hardness of BaF2 is 82, andit is verv sensitive to thermal shock, it is usualy applied to crvogenic imadina svstem, ens in space optical svstem and aseloptical system, beam spliter, filter, prism and window, The material has a certain degree of water solublity which is suitableto be used in dry environment

How Do BaF2 Optics Work?

How Do BaF2 Optics Work?

BaF2 Optics work by utilizing the unique optical properties of barium fluoride, a material that exhibits high transmission in the infrared range. As light passes through BaF2 Optics, it encounters a material with a low refractive index and minimal dispersion, resulting in minimal distortion and high clarity. This allows BaF2 Optics to accurately transmit infrared radiation, making them indispensable in applications requiring precise infrared imaging and detection.

What Are the Advantages of BaF2 Optics

1

Wide Transmission Range: BaF2 optics transmit from UV to mid-IR, suitable for applications like spectroscopy, UV lithography, and laser systems.

2

Low Absorption: BaF2 has low absorption in the UV and visible spectrum, ensuring high transmission and minimal energy loss.

3

Thermal Stability: BaF2 optics exhibit good thermal stability, maintaining performance in varying temperature environments.

4

Cost-Effective: BaF2 is relatively affordable compared to other UV-transmitting materials, making it a cost-effective choice for certain applications.
