Magnesium fluoride (MgF2)
MgF2-E: 193nm / 248nm / 355nm excimer, excellent uniformity, no small-angle grain boundaries;
MgF2-PS: PID 10.6eV and spectrum analyzer have low energy loss and stable light energy;
MgF2-W: Wave plate, high orientation accuracy, no small-angle grain boundaries, low stress;
MgF2-V: used in ultraviolet/infrared light sources, vacuum viewports, lenses, prisms, etc.;
MgF2-H: Hot pressing, mainly used for dome cover;
ICC has lithium fluoride material in ultraviolet/deep ultraviolet, which can be used for extreme ultraviolet light source, LED panel coating, ULTRAVIOLET detection and sensing.
LIF is highly water-soluble, and has strict requirements on optical processing and storage, and dissociation often occurs. Therefore, the archive of the polishing sheet is mostly used for plating a protective film.
With more than 10 years of processing experience, Intrinsic can meet the high precision and low chipping requirements of LIF processing, and better meet the needs of the market. Lithium fluoride is used in windows, lenses and prisms in vacuum ultraviolet, ultraviolet, visible and infrared.
Intrinsic silicon currently has three grades and is widely praised by customers.
SI-MIRROR grade: single crystal, mainly used in the galvanometer mirrors of various high and low power lasers, standard shapes or customized shapes, typical: no transmittance requirements.
SI-OPTICAL grade: single crystal, mainly used for infrared temperature measurement and imaging purposes such as optical lenses, filters, prisms, etc., typically: higher transmittance requirements.
SI-Wafer grade: single crystal, mainly used in semiconductors, IGBT modules, diodes and triodes, typical: resistance control is extremely strict.
Witness samples allow testing without handling the actual part, to ensure the coating process is accurate before moving forward with the optical component. And after coating, the witness samples are often used to measure reflectivity, transmission, and polarization, as well as humidity, temperature, durability, and salt fog tests. The witness material is should be the same as the substrate material and is almost always the industry standard of roughly 1” (25 mm/25.4mm) in diameter to accommodate the size of standard spectrophotometers tooling .
