Applications
Vacuum/deep-ultraviolet optical systems: UV spectrometers, UV lasers and lithography inspection. Research laboratories: wavelength calibration, spectroscopic systems and polarization paths. Infrared systems: near-/mid-infrared detection and thermal-imaging prisms. Medical optics: UV diagnosis and medical-imaging optical-path components. Aerospace and metrology: high-precision optical instruments, astronomical optics and standard-angle prisms.
Key Features
Ultrabroad transmission: 150nm–6000nm for vacuum UV, UV, visible, near-IR and mid-IR. Excellent deep-UV transmission: among few common crystals transmitting from 150nm, for vacuum-UV systems. Low dispersion/high homogeneity ensure accurate imaging, spectral splitting, wavelength calibration and polarization. Precision angles: tolerance to ±3″, flatness to λ/10. Full structures: right-angle, equilateral, roof, Dove, pentagonal, rhomboid, corner-cube and irregular. Physicochemical stability and radiation resistance suit research/medical optics. IV. Material advantages. Transmission 150nm (vacuum UV)~6μm (mid-IR), outstanding UV performance. Index n≈1.392, high Abbe number and ultralow dispersion for precise splitting. Moderate hardness permits polishing, angle and irregular fabrication. Softening point about 600℃ suits UV lasers and conventional optics. UV-radiation resistance for long-term UV paths. V. Types: right-angle (90°/45°), equilateral dispersive (60°), roof, Dove, pentagonal, rhomboid, retroreflecting corner-cube and custom irregular prisms with steps/holes/special angles. VI. Coatings: vacuum-/deep-UV AR 150–400nm; visible AR 400–700nm; near-/mid-IR AR 3–5μm; broadband AR 150nm–6μm; HR, beamsplitter and polarization layers; high-laser-damage-threshold coatings for UV lasers. VIII. Yasi Optical advantages. In-house cutting → grinding → polishing → angle finishing → coating → inspection. Nikon goniometers, ZYGO and optical dimensional instruments provide full inspection. Large sizes and small batches accepted. Standard stock and rapid custom delivery. Clean washing/vacuum packaging ensure UV-grade surfaces. IX. Quality: every lithium fluoride prism passes angle, flatness, dimension, surface-quality and transmission tests before shipment for reliable UV/IR optical paths.
