Magnification meaningin microscope

Calcium fluoride (CaF2) is a crystalline compound with a cubic crystal structure. This popular optical material can be used across a wide range of ultraviolet (UV), visible, or infrared (IR) applications due to its unique optical properties.

Our mirrors made from calcium fluoride have been used in various laser and industrial machinery, including excimer lasers, free-space lasers and cryogenically cooled thermal imaging systems.

Here at Global Optics, we're experienced and trusted suppliers of calcium fluoride optics, from lenses and windows to prisms and other optical components.

Magnifymeaning

magnification中文

Low refractive index: Calcium fluoride has a relatively low refractive index of 1.43 or homogeneity, making it useful for optical components such as lenses and prisms.

Binocularsmeaning

Thanks to its low refractive index, CaF2 windows are also ideal for high-precision applications, such as microscopes and telescopes.

Overall, the combination of high transmittance, low absorption, low dispersion, and high thermal stability makes calcium fluoride a useful material for a variety of optical applications.

What is themeaning ofresolution

High resistance to radiation damage: Calcium fluoride is highly resistant to radiation damage, making it useful in applications that involve radiation exposure.

Low absorption: Calcium fluoride has a low absorption coefficient, and therefore can transmit light with minimal loss. This property makes it useful for optical components in high-power laser systems.

High damage threshold and mechanical strength: The mechanical properties of calcium fluoride include an impressive ultimate tensile strength (UTS) of 34.1 to 157 MPa. CaF2 also offers excellent water, chemical, and heat resistance.

Our calcium fluoride optical windows are ideal for spectroscopy applications, UV laser systems and fluorescence imaging, offering excellent performance, as well as water and fogging resistance.

High transmittance: Calcium fluoride has a high transmittance across a wide range of wavelengths, making it a useful material for applications in ultraviolet, visible, and infrared regions of the electromagnetic spectrum.

At Global Optics, our CaF2 prisms can be used for wavelength separation and image rotation applications, and IR and UV optics.
