Calcium Fluoride Barium Fluoride Zinc Selenide CaF2 Total Transmission (Uncoated) ) mm sample thickness Wavelength (um) Barium Fluoride is transparent from the UV to the IR. The material is less resistant to water than CaF2. The material is relatively hard, but very sensitive to thermal shock. Of the optical fluorides it is the most resistant to high-energy Silicon Piano-Convex lenses are an ideal choice particularly well suited for imaging, biomedical, With a transmission range from 600 nm - 16 mn, zinc selenide Piano-Convex lenses absorption coefficient, these lenses are also particularly...

Optical Elements Polarization Optics Optical Isolators Optical Systems Optics Kits Spherical Lenses Achromatic Lenses Aspheric Lenses Cylindrical Lenses Spectral Filters N-BK7: Best Form Lenses Best Form optics are designed to minimize spherical aberration while still using spherical surfaces to form the lens. Each side of the lens is polished so that it has a different radius of curvature, making these lenses more expensive than plano-convex or bi-convex lenses. Ideally, Best Form Lenses are best used at infinite conjugates in high-power applications where As the diameter of a beam...
