Optical Design, Development and Production

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. The metallic mirror coatings have high reflectivity over the widest spectral region, while the broadband dielectric mirrors have a narrower spectral range of operation; the average reflectivity throughout the specified region is greater than 99%.

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.

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:

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

They are used for Olympus bio microscope of UIS2 optical system, such as CX21, CX31, CX41 etc. With very excellent imaging quality and very high cost performance.

There’s only very small differences in the blind inspection between original and ours. They could completely replace original objectives of Olympus MPLN (M Plan achromatic), you just need to do a simple fine adjusting when use.

• Apply for microscope of infinite corrected optical system with tube lens FL 180mm, such as Olympus microscope.
• DIN 45mm standard, All optics are AR coated.
• All 40x to 100x objectives have spring-loaded (retractable) front ends in order to prevent slide damage.
