Optical Filters Custom Kinds Of Substrate CLZ Product Description Optical Filter, an optical element. It is a tool used to select the desired radiation band of light to transmit and filter out the unwanted light waves. It is a plastic or glass sheet made by adding special dyes, and its main characteristics are good transmission, good spectral characteristics, mainly selective transmission or blocking the transmission of light of specific wavelengths or bands. They are widely used in spectroscopy, fluorescence microscopy, clinical chemistry and mechanical vision industry. Optical filters are also optical components on or independent substrates coated with one or more layers of dielectric film or metal film to change the characteristics of light wave transmission. The use of light waves in these films in the transmission of the characteristics of the phenomenon, such as transmission, absorption, scattering, reflection, polarization, phase changes, and so on, and then design and manufacture a variety of products to achieve the purpose of scientific and engineering applications.

It is essential to maintaining the accuracy, repeatability and traceability of the coating process.

Silicon windows and Silicon lenses for Infra-Red Imaging Systems Product Description Infrared lenses are lens assemblies optimized for light processing in the infrared region, including near-infrared, short-wave infrared, mid-wave infrared, and long-wave infrared. IR lenses are optical lenses that use specific substrates or anti-reflective coatings to maximize performance for applications above 700nm including thermal imaging, FLIR or spectroscopy. The single crystal of silicon used in semiconductors has low absorption in the infrared wavelength of 1.2 - 7μm and it can be used as an optical element of infrared light.  Silicon (Si) is a hard material and has good transmission in the IR bank, it is a good choice to make IR windows to protect other elements of lens systems. Silicon optics are used in a variety of infrared applications operating in the 1.2 - 7μm wavelength range, including near infrared imaging or infrared spectroscopy. Silicon's low density (2.329 g/cm 3 ) is ideal for weight- sensitive applications. Silicon has a Knoop hardness of 1150, which makes Silicon Lenses harder and less brittle than comparable germanium optics. And refractive index of about 3.4975 at 1.357µm through to 3.4176 at 11µm, it is a good choice to use in broad-spectrum thermal imaging systems. Sometimes, the Si lenses will be used with Ge and ZNSE in the optical systems to form well-corrected. We use our expertise to design and manufacture high-performance IR Optical Lenses and assemblies for our customers.

Custom Plano-Concave Lenses for Laser Optics Product Description Plano-concave lenses convert incoming parallel light rays into diverging beams that appear to come from a point in object space, the so-called imaginary focal point. Like plano-convex lenses, these lenses have the least image aberration at absolute conjugate ratios greater than 5 or less than 1/5. For this reason, plano-convex lenses should be placed so that the parallel beam enters the curved surface of the Optical lens. However, when a plano-convex lens is used to disperse a high-power pulsed laser beam, this orientation of the lens can be detrimental, with stationary reflections from the curved surface creating secondary focusing that can damage the optics in front of the concave lens and even cause the laser to collapse at that point. Therefore, in high power applications, the concave surface should be oriented in such a way as to avoid secondary focusing. CLZ supply high-quality optical components to customers in the laser measurement and laser scanning industry for applications such as distance monitoring systems, laser scanning, and mapping. Our high-quality optical components include: Single lenses, Condenser lenses, Doublet lenses, Triplet lenses, Optical windows, and optical Filters. The materials include Optical glass, Fused Silica, Silicon, Sapphire, etc. And our V coatings can suit all laser options available with R<0.25%-0.5%.
