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.

Acidity coefficient (pKa): -2.62±0.10 (Predicted) Sensitivity: Moisture sensitive BRN: 124237 Use 1: Mainly used to prepare reactive dyes Use two: used in organic synthesis. Overview: Cyanuric fluoride is a key intermediate in the synthesis of fluorinated s-triazine reactive dyes. Compared with traditional chlorotriazine reactive dyes, fluorinated s-triazine reactive dyes have the following five advantages: 1. Energy saving, low dyeing temperature (medium temperature type) 60℃, lower than KE type reactive dyes and equivalent to M type reactive dyes. 2. Emission reduction, environmental protection, and high color fixation rate. The color fixation rate is 15 to 20 percentage points higher than that of the corresponding chlorotriazine reactive dyes. It can not only improve the utilization rate of dyes but also reduce environmental pollution during the printing and dyeing process. 3. The dye has good stability. 4. High peroxide resistance and stability. 5. Not restricted by AOX regulations.
