Spherical lenses are used to focus, form images, and to collimate or expand light. They are used in almost every optical system, from high power, deep-UV lasers to low-cost condensers delivering light to a detector. CVI Laser Optics has solutions for them all. Our vast selection of lens shapes, materials and lens quality options will allow you to find the right balance between performance and cost for even the most demanding application.
Aside from shape, material type and manufacturing quality are the most important factors that determine lens performance.
Our spherical lens catalog is motivated by laser applications, with a strong focus on high quality and high damage threshold materials. We offer lenses constructed of N-BK7, UV-grade fused silica, excimer-grade fused silica, CaF2
, and N-SF11 in diameters ranging from 2.5 to 76 mm, and focal lengths from 3 mm to 10 m. All are available with user-specified antireflection coatings, ranging from a V-coat to dual 1064/532 and broadband, high transmission AR coatings .
Our high quality laser grade lenses offer high laser damage threshold, maximized by our low-loss antireflection coatings, and are well suited to diffraction-limited applications. They are designed and manufactured to λ/10 surface figure with low surface defects to ensure low wavefront distortion performance and minimize scatter. Our standard lenses are ideal for low power and imaging applications, where low wavefront distortion requirements and scattered light concerns are less critical. Our aspheric glass condenser lenses are an economical option for low-power light collection applications such as collecting light from a source, illuminating a target, or focusing light on a detector. They offer low f-number with minimized aberrations and high throughput.
Whatever your application may be, CVI Laser Optics experts are on hand to assist you with ray-tracing analysis of simple catalog-component systems, and can guide you to the right catalog or custom lenses for your particular needs.
