Optical mirror is a very important optical element in the laser. Its performance is an important factor that affects the quality of laser beam and output power, such as the level of reflectivity, the size of the deformation, the speed of heat transfer, and whether it can maintain its optical performance for a long time. If the reflectivity is not high enough, the attenuation value is too large, and the gain cannot reach the threshold, then the laser cannot emit light. When optical mirrors are used as a reflective element inside and outside the ordinary optical cavity, there will also be a problem of the large loss of optical power. The substrate material of commonly used laser mirrors Optical reflector is generally used as a tail mirror, a mirror that turns the direction of the optical path in a laser system. The substrate material is usually molybdenum, fused silica, oxygen-free copper, silicon, etc. Fused silica mirror has high transmittance from ultraviolet spectrum to the infrared

  UV/VIS spectrometry is a qualitative, quantitative and structural analysis method established based on the absorption characteristics of material molecules to electromagnetic waves with a wavelength of 200-760 nm. Light with long wavelength has low energy. Light with short wavelength has high energy. Optical elements in the UV/VIS spectrophotometers plane mirrors, spherical mirrors, optical filters, interference filters, optical gratings, optical prisms, plano-concave lenses Optical system of UV/VIS spectrophotometers The composite light emitted by the tungsten lamp and deuterium lamp passes through the optical reflector and the incident slit, and enters the monochromator. The monochromatic light diffracted by the optical grating is focused by the collimator lenses and converges through the exit slit. When the light beam reaches the chopper, the light for a period of time becomes the reference light path. The light for another period of time is transmitted as the sample light path. T

First use fairly pure raw materials and equipment, which are carefully designed to avoid pollution of harmful substances. Typically, block glass is made by filling a certain amount of glass melt into bulk, then placing it in molten form for a period of time to settle, and then slowly cooling it to solidification at a carefully controlled rate. Slow cooling allows annealing, that is, reducing internal mechanical stress. Very slow and well-defined annealing stages are important, especially for bringing stress-induced birefringence to very low levels, as well as for reaching constant refractive index values. Precision optical glass is usually provided in the form of fine annealed glass, with a reference annealing rate of K /h.2, for example. Glass Optical Domes Other forms of supply of raw optical glass are large str

  As a   Dome Lens Manufacturer , share with you. One of the most common inquiries we are asked is: what size dome should I use? Underwater Camera Dome Well, the answer mostly depends on what style of shooting you do, what lens you are aiming to use in the dome, as well as often your budget plan. When we talk about the size of the dome port we are describing the general size of the acrylic aspect. Other variables with domes are the elevation of the acrylic element, as well as the size of the port itself. We have done the effort and also optimized the height of the acrylic for all diameters of dome so you do not need to fret about this. However, you will certainly require to take into consideration the size of the port based on what lens you are aiming to utilize in the dome. We will certainly discuss this in the direction of completion of this post. First, allow's consider the dome ports we provide, and what the advantages and disadvantages of each. 4-Inch Dome-- The very best for

  As an   Optical Domes Supplier , share with you. Sapphire window is an extremely thin piece optical component manufactured from single-crystal sapphire. When it calls for to maximise the transmission, reduce the representation and also, shield the important electronic or mechanical parts from the extreme environmental condition, this sapphire window used in the setting up. Occasionally it is described as sapphire lens, but to be specific it is not. The sapphire lens has one or all surface bent, Whereas the sapphire window has all surface areas are flat. Sapphire Window Why we should use a sapphire window? The solution to why the  Sapphire Window  hinges on the excellent desirable building of sapphire material for a lot of industrial application. When we discuss sapphire, we thought about sapphire gemstone, of course that blue one, which is found in nature. it remains in limited resource, as well as very costly. This sapphire window made from synthetic sapphire, which is produced in t
