Description

MgF2 Optical Window Magnesium Fluoride Optical Window
Magnesium fluoride crystal is a birefringent crystal with high hardness, good mechanical properties, and wide light transmission range (120nm-7500nm). It has a high transmittance, especially in vacuum ultraviolet bands. It is suitable for windows and focusing mirrors of deep ultraviolet and excimer lasers.

MgF2 Optical Window Magnesium Fluoride Optical Window has excellent bandwidth transmittance and can transmit deep UV and mid-infrared. DUV transmission makes it ideal for hydrogen Raman lines, UV radiation sources and receivers, and excimer laser applications. Magnesium fluoride is a powerful material, which can be used to resist chemical corrosion, laser damage, mechanical shock, and thermal shock. It has a Knoop hardness of 415 and a refractive index of 1.38.

Feature
All-optical spectrum range: 200-6000nm
Ultra-wide spectrum application, covering UVA ultraviolet, UVB ultraviolet, visible and infrared bands
When applied to the optical system, there is almost no phase difference and no birefringence effect
Application: deep violet optical application, laser system application, infrared system, and protection window application, etc

Processing range:
WDQ OPTICS can process and order all kinds of magnesium fluoride windows, magnesium fluoride plane mirrors, and magnesium fluoride plane windows for you

Technical parameters:
Material: magnesium fluoride MgF2
Outer circle: 4mm-500mm
Parallelism deviation: < 30s
Surface accuracy: > λ/ ten
Surface quality: 40 / 20
Effective caliber: 90%
Coating: coating can be carried out according to customer requirements

Application:
it can be used in wave plate, laser system, coated crystal, vacuum window, PBS light source, microscope, optical instrument, etc. It is used as optical window material in vacuum ultraviolet to the infrared band and is a birefringent optical material for polarization optical devices in the ultraviolet radiation region.

Magnesium fluoride has only a slight effect under high-energy radiation. It is the preferred ultraviolet radiation optical element for space workstations. It has been proved that the laser damage threshold of magnesium fluoride material is high and does not produce a color center. Compared with calcium fluoride material, it is more suitable for the optical window material of stimulated excimer laser. The chemical composition of magnesium fluoride determines that magnesium fluoride is the preferred material for a fluorination environment.
