Metallic Mirror Coating

Image
Different types of parabolic, spherical, and flat mirrors are produced having different types of mirror substrates . These products have a variety of metallic and dielectric coatings that make them suitable for various applications. The various types of mirror coatings include Protected Aluminum, Enhanced Aluminum, UV Enhanced Aluminum, Bare Gold, and Protected Gold etc that are used for visible applications. UV and DUV enhanced aluminum is used for UV and visible applications while Bare and Protected Gold offer high reflectance for near Infrared and Infrared Wavelength. First Surface and Second Surface Mirrors All the mirrors you use are first surface mirrors. This mirror has a high reflectance coating deposited on the front surface of a variety of different types of glass, metal or semiconductor substrates. The other surface of the mirror may be clear or ground and the mirror is oriented so that the coating faces the source. They are widely used in precision optics ap...

Benefits of Fused Silica

Image
Fused Silica is the highly pure, non-crystalline material and is the most preferable choice for making mirror substrate, high performance lens, and simple stable tool. It has many benefits that make it a priority choice among the users. Some of the benefits of Fused Silica are: Range of Transmission: A fused silica produces the high throughput over a wide range of the spectrum. A standard UV fused silica transmits more than 90% in the wavelength range of 200nm to 2 microns with the least deviation at 1.4-micron wavelength. The IR grade fused silica achieves more than 90% transmission within the wavelength of 200 nm to 3.5 microns. Other fused silica varieties allow the transmission in the high-power semiconductor, extreme UV region of 248 nm and 193 nm due to the presence of some impurities.  Fused Silica is the most superior and versatile glass material as its transmission range lies within the limit of most of the optical glasses. Low Thermal Expansion ...
