Custom Optics
Wavelength Opto-Electronic is Singapore’s leading custom optics manufacturer, dedicated to producing high-quality optical components for various industries. We utilize cutting-edge technologies and manufacturing techniques to design, prototype, and manufacture custom optical lenses, optical mirrors, and many other optical components to meet your requirements. As a trusted custom optics manufacturer, we are committed to providing exceptional customer service and delivering innovative solutions to you.
Optical Materials
We'll start with raw materials used for the making of optical lenses. Lens materials are available in glass, crystal, metal, and plastic.
Optics Manufacturing
The production of your desired lens starts. We've a range of production equipment and metrology used in the manufacturing process.
Optical Coating
Various coating solutions are available, such as AR, HR, PR, BC, and many more options, to meet your coating needs.
QA & QC
We closely monitor our manufacturing and inspect our products to ensure consistent quality is being delivered.
Optical Assembly
Before assembly begins, all mechanical components and work surfaces must be thoroughly cleaned to prevent contamination. Any dust or debris present at this stage can significantly impact optical performance, especially in high-precision systems. The cleaning process typically starts with compressed air to remove loose particles. This is followed by a liquid cleaning method to eliminate residues. Care must be taken to ensure that delicate optical coatings are not damaged during this process.
Proper handling is critical throughout the assembly process. Optical components should be handled using vacuum chucks or appropriate gloves to prevent oils and contaminants from transferring from fingers onto the surfaces. During assembly, lens elements and spacers are inserted sequentially into the housing according to the optical design. Each component must be placed carefully to maintain the intended optical path and spacing.
Alignment is then performed using a laser-based setup to verify precision. By observing beam propagation and reflections, adjustments can be made to ensure correct positioning. Spacers are often used to fine-tune the distances between elements for optimal performance. Once alignment is achieved, the components are secured in place. This is typically done by tightening threaded retaining rings or, in some cases, applying optical-grade adhesives depending on the design requirements. Finally, the assembled system undergoes inspection and testing. This includes a final cleaning check and optical performance validation, such as Modulation Transfer Function (MTF) testing, to ensure the system meets the required specifications.

Silicon Micro Lens Array
We’ve produced a micro lens array using diamond turning (Nanotech 250UPL with 3 axis). The process involved slow speed servo (C-Axis) with a cycle time of 50Hrs (including roughing, semi-finish, and finish). Targeted results are Rq-10nm and surface quality 60-40, we’ve achieved results of Rq-6 to 9nm and surface quality 60-40.
Off Axis Parabolic Mirror
These off axis parabolic mirrors, copper (F250 and F100) and aluminum (F100 and F12.5), are machined using 3 axis diamond turning machine. Targeted roughness Rq<10nm and form error<0.6 microns, we’ve achieved results of Rq= 10 nm and PT=0.25 microns.
Bi-Conic Copper Mirror
We use 3 axis diamond turning machine to make a bi-conic copper mirror using slow speed servo process. Targeted roughness Rq<10nm and form error<0.6 microns, we’ve achieved results of Rq 3nm and 4nm, and PT=0.3 microns and 0.6 microns.
