The aspheric mirror can image within the wavelength range of 0.8-12um, without interference from weather changes and light conditions, with stable imaging, clear image quality, and small aberration.
Application:
It is mainly used in night imaging, instrument flaw detection, infrared thermal imager, infrared temperature measurement, infrared distance measurement and other fields.
The aspheric lens corrects spherical and chromatic aberrations by continuously changing the radius of curvature from center to edge along the main optical axis, resulting in improved spot quality. It is optimized to minimize aberrations by adjusting the conic constant and aspheric coefficient.
Coligh offers both uncoated and AR coated aspheric lenses with a range of coating options from UVA to IR2, suited for various applications including barcode scanning, laser alignment, and optical imaging.g from UVA to IR2 across the spectrum.
You can get Coligh’s aspheric lenses, also called aspheres, in molded, CNC-polished, or MRF-polished versions, with or without anti-reflection (AR) coatings. Aspheres are commonly utilized to collimate light as it emerges from a fiber or laser diode. Their surface is specifically engineered to eradicate any spherical aberration.
At Coligh Optics, we offer a range of biconcave lenses made from various materials such as BK7, fused silica, CaF2, K9, among others. These lenses can be tailored to meet specific requirements, and we provide customized options to our customers. Additionally, we offer anti-reflection coatings for different wavelengths based on the intended usage.
biconvex lenses are optical lenses that have two convex surfaces with the same radius of curvature. They are commonly used in various imaging devices and for focusing laser beams. Coligh Optics is a company that produces high-quality biconvex lenses for a range of beam focus applications.
Negative meniscus lenses have a convex side and a concave side, with the edge being thicker than the center. This design can effectively reduce spherical aberration. These lenses are frequently used together with other lenses to lower the numerical aperture and are widely used in beam expander applications. Coligh Optics offers negative meniscus lenses in various materials and specifications, and can customize them according to specific customer requirements.
At Coligh Optics, we take pride in our ability to manufacture cylindrical lenses that meet a wide range of specifications and requirements. With our advanced manufacturing capabilities, we can produce cylindrical lenses with varying radii, using different high-quality glass materials such as H-K9L and fused silica.
At Coligh Optics, we offer a broad range of Plano Concave Lenses optimized for the 350-1580nm spectrum. Our lenses range in diameter from 10 mm to 300 mm and are available in both coated and uncoated options. Our team of design engineers can collaborate with you to create custom lenses that meet your specific application requirements.
A plano-concave cylindrical lens is a type of cylindrical lens, which is a lens that has a curved surface with a cylindrical shape. Unlike spherical lenses, which have a curved surface with a spherical shape, cylindrical lenses have a curved surface with a cylindrical shape that is either convex or concave. This type of lens is used to correct or adjust the focus of light in one direction only, either horizontally or vertically.
A plano-convex lens is a type of lens that consists of a flat surface and a convex spherical surface, and possesses a positive focal length. This design makes it particularly well-suited for concentrating and focusing light, making it a valuable component in applications involving emitters, detectors, and lasers.
Coligh Optics provides a selection of Positive Meniscus Lenses produced using a variety of materials such as BK7, fused silica, CaF2, Znse, and more. These lenses can be customized to meet particular demands, and we provide personalized alternatives to our clients. Moreover, we offer anti-reflection coatings for a range of wavelengths according to the desired application.
