Magnesium fluoride(MgF₂) is an optical crystal with excellent overall performance from vacuum UV to mid-IR, short transmission cutoff, high hardness, chemical stability, and very low dispersion. It serves beamsplitting, folding, and collimating prisms for vacuum-UV paths, deep-UV spectrometers, lasers, astronomy, and precision inspection. Scysgx uses high-purity single-crystal blanks for right-angle, equilateral, Dove, pentagonal, roof, polarizing-beamsplitter, and special-shaped prisms. Sizes span 1–1000mm, in industrial and precision research grades. Angular accuracy, flatness, and surface finish can meet research-instrument standards;multiband coatings provide stable UV/IR broadband prism solutions.

Vacuum/deep-ultraviolet systems: UV spectrometers, detectors and lithography prisms. Research: spectroscopic experiments, wavelength calibration, polarization and precision optical paths. Astronomy/aerospace: observation instruments and wide-spectrum detection components. Lasers: deep-UV turning, collimation and beamsplitter prism assemblies. Precision inspection: optical metrology, analytical instruments and precision imaging.
Ultrabroad transmission: 120nm~7μm spans vacuum UV, deep UV, visible and mid-IR with high transmission. Excellent 120nm vacuum-UV performance suits lithography/detection. Ultralow dispersion/high Abbe number minimizes chromatic effects for precise splitting, imaging and alignment. High hardness, scratch/wear resistance and structural stability suit outdoor/continuous use. Stable chemistry, no deliquescence, acid/alkali and environmental-corrosion resistance preserve optics under complex temperature/humidity. Precision fabrication provides small angular tolerances, high flatness and good surfaces for instruments. All standard/special-angle/irregular structures customizable. IV. Material advantages. Transmission from 120nm surpasses ordinary glass/most crystals in deep UV. Moderate index/very low dispersion provide excellent imaging/splitting. High hardness/impact resistance resist scratches and retain structure. High melting point/low expansion reduce high-/low-temperature deformation. Humidity/weathering resistance and no deliquescence suit space, field and laboratory use. V. Types/customization. Right-angle, equilateral dispersive, Dove, pentagonal, roof, rhomboid, corner-cube and polarizing beamsplitter prisms. Arbitrary side lengths/thicknesses; special apex/reflection/refraction angles; steps/slots/holes/irregular shapes; precision polishing, ultraclean washing and controlled chamfers; band-matched functional coatings. VI. Coatings. Vacuum-/deep-UV AR 120–400nm; visible broadband AR for normal imaging; mid-IR AR 3–5μm; dielectric/metal HR for beam turning; polarization/beamsplitter layers; high-laser-damage-threshold layers for deep-UV lasers. VIII. Yasi Optical advantages. Integrated in-house blank cutting, grinding, polishing, angle correction, coating and inspection. Interferometers, precision goniometers and optical dimensional instruments control all parameters. Small/large batches and mature large-size magnesium fluoride fabrication. Standard stock and controlled drawing-based custom lead times. Ultraclean washing/vacuum moisture-proof packaging ensure surface quality/storage stability. IX. Quality. All magnesium fluoride prisms pass strict flatness, angle, dimensional-tolerance, visual-surface and spectral-transmission tests before shipment. Shock-/moisture-proof packaging suits long-distance transport, laboratories and long-term industrial installation.
