Lenses
Lenses have many applications in range from the simple collection of the scanning of laser beams to precise imaging and image transferring. Lenses are classified as singlet, achromatic cylindrical, and aspherical lens according to the different applications.

Selecting the proper lens for your application requires making a number of choices. Many considerations include: lens shape, conjugate ratio, f/number, transmission, wave front distortion, scattered light, anti-reflection coating, and cost. Base these, material is also an important factor for you to choose products. In ATE, the material of BK7, Fused silica, CaF2 and MgF2 as standard. Other materials are available upon requirement.

Precision optics for professional use and with the right hardware

Prisms

Optical prisms is based on the principles of optical reflection and refraction.

In order to change the direction of the image and the effect or light, the system is fed in a smaller space by the specific optical glass and it is designed as a geometry.

The production of optical prisms is based on planar grinding line, optical coating lines and optical glue lines. With the fixture precision and customized.

Mirrors

We design and manufacture a great choice of various high and partially reflecting mirrors for the spectral range: UV, Visible, Near Infrared Regions.

Based on optical grinding and optical coating (PVD & IAD), the main mirrors we manufacture are metallic mirror and dielectric mirror.

Filters

Filters alter the characteristics of a beam of light either by changing the overall intensity of the beam without affecting its spectral content or by changing or separating the spectral content of the beam through wavelength-selective absorption or reflection.

Our optical filters are manufactured with IAD coating systems to ensure that the coatings meet your damage threshold, environmental stability, temperature cycling and durability requirements.

Beamsplitters

Beamsplitter is used to split or combine two perpendicular polarization laser beam.

The performance of an beamsplitter depends on the coating specifications. With a certain light angle through the PBS, specific wavelengths P polarized light, S polarized light through high, while making P high reflecting light and S light separation.

It is the important parts of optical interferometers, usually used in laser system and the optical fiber communication system. ATE production of optical splitter information is as follows:

Optical lenses

Tab Content goes here

The main lenses we manufacture are FA Lenses, Micro Objective Lenses, Telecentric lenses and Line Scan Lenses.

We can provide lenses design services according to the customer’s demands. Our products are used primarily for machine vision inspection, identification of shape and defect, print inspection, medicine testing, ceramic inspection, bar code and tag detection, fastener testing, connector testing, laser micromachining and etc.

We will follow the demands of the world market intensive, to improve our technologies and production capacity continually.

Manufacturing Capacity:

The barrel is often given a 25–50-µm larger diameter than the lens outer diameter to provide room for loading the optics without jamming.
Relief grooves or vent holes should be created in the barrel to relieve pressure when inserting elements into the barrel.
The retaining rings and spacers should contact the lenses at the same diameter that the seats do; this avoids imparting a moment in the lens, causing distortion.
The axial location of the lenses should not be determined by the retaining rings. Tightly ﬁtted rings can cause stress in the lenses due to wedge error.

To avoid this problem, either the ﬁt of the retaining rings should be loose or some compliance should be provided (i.e., an O-ring). The lens position should be deﬁned by machined seats in the barrel or by precision spacers. In a straight-barrel design, all lenses are the same diameter and are separated by spacers. The assembly is typically held secure by a threaded retaining ring at the end.

Simple, low-cost, easy assembly
● Precision limited mainly by the precision of the elements

In a stepped-barrel design can accommodate lenses of varying sizes and uses spacers and/or machined seats to hold the lenses at the proper separation. If the seats are machined into the barrel, tight tolerances are required on the wedge of each lens.

More complex machining required than a straight barrel, easy assembly
● Precision limited by the machining: 50 µm is common, 10 µm is possible
● FA Lenses
● Line Scan Lenses
● Telecentric Lenses
● Micro Objective Lenses
● Endoscope Lens
