Telecentric lenses are used in innumerable vision applications, and in particular they form the critical component of the optical system when precise measurement is required. Non-contact measurement applications demand the use of such lenses which, thanks to their low distortion, can eliminate perspective errors (parallax effect) due to imprecise positioning or objects with strongly 3D geometries.

In machine vision applications, choosing the right lens is essential to obtaining high quality images suited to efficient and accurate processing. In many cases, the lens is the starting point for the construction of a machine vision system, although the result also depends on the resolution of the camera and the pixel size.

Thin film interference filters are virtually absorption free – providing superior transmission, rich saturated cyan colors, and true lifetime performance. They also have a steep edge transition between the shorter wavelength transmission band and the longer wavelength reflection band – much steeper than colored glass or polymer gels.

Opto Engineering’s vast range of fixed focal length lenses includes lenses for small, medium and large sensors, with a variety of focal lengths, apertures and resolutions.

PIXELTEQ’s 45° dichroic mirrors are shift-free color filters, dielectric coated interference filters which transmit certain regions of the visible spectrum and reflect others with high efficiency. The filters mirrors are manufactured with proprietary sputtering technology which makes them extremely stable to changing operating temperatures and harsh environmental conditions.

Forty-five degree dichroic mirrors and filters guide light by selectively transmitting and reflecting different wavelengths – commonly used to combine light from multiple LEDs or lasers into a common light path, or in reverse separating white light or fluorescence excitation and emission bands into discrete components. Since dichroic filters are angle-dependent, the standard versions of 45° dichroic filters are designed to operate at a 45 degree angle of incidence; custom angles and illumination sources are available on request.

Color filters are commonly matched or combined with other types of filters to optimize performance in your specific application. In many cases, an optimized OEM design combines multiple coatings to enhance performance, size, and weight of the device. Some of these complementary filter types include:

Opto Engineering offers a vast range of precision telecentric and bi-telecentric lenses for the most diverse requirements of the market: models for high and low resolution area and line scan sensors in a variety of magnifications and working distances; classic, compact and flat lenses, along with standard and custom solutions. The range also includes special telecentric lenses: lenses with integrated liquid lenses, zoom lenses, optical benches and other special products. Opto Engineering 360° view lenses are unique designs that make it possible to inspect an entire product while reducing the number of components in the vision system. Thanks to their special optical design, just one camera is needed to simultaneously inspect multiple surfaces of an object: the bottom and internal surfaces, or the top and external surfaces. The family includes multi-view lenses which give a single image of the object containing a variety of points of view. Many of these 360° view lenses represent an innovative way of resolving vision applications, previously considered impossible, in a simple and effective way: they are used in numerous industries, from food & beverage to pharmaceutics and automotive. Some of these extraordinary optical innovations are the fruit of Opto Engineering’s R&D, have been patented internationally, received numerous awards, and constitute an extremely valuable resource for our clients.
