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%.

A biconvex lens means that both surfaces of the lens are convex. Its focal length is positive and mainly for the function of focusing. It is commonly used in imaging relay system and object imaging at finite conjugate distance. The smaller the conjugate ratio is, the smaller the aberration will be. Oplens can not only customize the common plano-convex lens of N-BK7 or fused quartz, but also customize the biconvex lens of any glass material.

An achromatic lens is a lens designed to minimize chromatic aberration and spherical aberration. Two-plate achromatic lens is one of the simplest achromatic lenses, which can be divided into two types: double agglutination and double dissociation. Of course, achromatic lenses can also be composed of multiple lenses, depending on their uses. The achromatic lens with large aperture is usually separated and assembled in the frame with excellent comprehensive performance. Achromatic lenses are widely used. A multi-lens optical system usually consists of several achromatic lenses. High quality microscopic objective lens and photographic lens are all complex lens combination systems which eliminate both achromatic and other monochromatic aberrations. Oplens can produce single layer or multi-layer anti-reflective films with all kinds of coating materials on both outside surfaces. Their performance is superior to that of all single element lenses.
