Melles Griot offers a family of four distinct, high-performance telecentric lenses for use in machine vision, metrology, and precision gauging applications. All provide low optical distortion and a high degree of telecentricity for maximum, accurate image reproduction, particularly when viewing three-dimensional objects.

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.

Spherical Lenses
MediVision Optics offers extensive lens manufacturing capabilities. Close to four thousand test plates published in Zemax and Code V, allows the designers to easily choose the closest radius for their design.
Specifications Achromatic Doublet Lenses:
Cylindrical Lenses
Meniscus Lenses
Singlet Lenses
Triplet Lenses
Focal Length: up to +/- 1%
Centration : up to 1 arc minute
Sizes: 4mm to 400mm
Diameter Tolerance : /- .02mm
