The UQG Custom Made Optical Lenses Range
UQG manufacture a custom made range of lenses to standard or custom supplied specifications. Our production workshop can accommodate prototype/R&D, batch runs to production quantities.
Our optical lenses are used from simple collection of light to precise imaging made to precision or commercial quality.

A sphere is the most common type of optic where at least one surface is a segment of a ball. Spheres are made with a radius of curvature from very short, on the order of 1mm, to very long, where plano is an infinite radius. Spheres are found in camera lenses, machine vision systems, focusing optics, and similar applications.
Optimax has one of the world's largest test plate (radius masters) libraries for making spheres. By utilizing existing test plates, which are certified to /- 0.01%, we can minimize the overall cost of a lens. In addition, Optimax can make test plates for special radii. We also make transmission spheres for interferometric testing of surface irregularity to 50th wave.
Optimax inspects 100% of all optics and provides test data with prototype orders. We utilize state-of-the-art metrology and provide on-time delivery guarantees to ensure your satisfaction!
Optimax can provide optics complete with BBAR, V-coat, and mirror coatings. We have four electron-beam coaters supported by a Perkin-Elmer Lambda 900 Spectrophotometer. For more details please see our Coatings data sheet.

All Moritex Telecentric lenses come with the option of a coaxial illumination port. This gives even Telecentric lighting for our range of lighting products.
This is useful for accurate positioning and flaw recognition in complex subjects.
Moritex produce both Zoom and Fixed Magnification lenses for a wide range of working distances and magnifications.

Aspheric Lenses
Aspheric lenses offer better performance by reducing spherical aberrations at low f-numbers. These lenses are ideal for high-throughput condensing, collimating and imaging applications. MediVision Optics offers unique manufacturing capabilities by grinding and polishing aspheres during the production process. Unlike conventional manufacturing techniques, our capabilities allow us to produce components which offer better surface finish and tighter tolerances.
Materials: Bk7 or equivalent
Diameter Range : 4mm to 50mm
Diameter Tolerance: +/- .2mm
Paraxial Focal Length Tolerance : /- 3%
Surface Quality : 60-40
Rear Surface: Spherical Convex or Concave

The plano convex lenses listed are made with BK7 glass however any glass type may be used. The lenses are designed to work best at infinity or near infinite conjugates.
The lenses have a standard AR coating but any type of multilayer coating may be ordered. Most lenses are in stock and can be shipped within 24 hours. Westech can produce a custom lens from any drawing or specification.

Micro-Optics and Optical Precision Structures
The miniaturisation of components and assemblies for equipment necessitates the miniaturisation of optical components.
Micro structures such as Fresnel and diffractive optics are required to achieve certain optical effects. Many of these mini and micro optical elements can only be manufactured using plastics.
Micro components have diameters less than 3 mm, sometimes less than 1 mm. Micro-optical parts, which are integrated in larger components, often measure only a fraction of a square millimeter and weigh only a few milligrams.

JENOPTIK Polymer Systems GmbH and MEMS Optical Inc. (also belonging to the Jenoptik group) have developed a double-sided microlens array in plastic. Due to a unique proprietary tooling this array can be reproduced for series production.
A double-sided microlens array enables, among others, homogenization of laser sources as well as beam guidance in laser projection systems. The new technology allows for an array precisely aligned front-to-back in the µ-area.
