OSLENS-Mastering in optical component design, development and production

Ocean Optoelectronics Technology masters in the design, development, and production for LED modules and non-imaging optics lenses. The applications combining LED and non-imaging optics ranges widely from basic LED single component design (TIR lens lighting) to complex visual application design (Naked-eye 3D).

Non-imaging Optics - Precision optics

We can roughly divide non-imaging optics into precision optics and ultra-precision optics based on accuracy. Precision optics manufacturing can meet most needs for general led lighting, such as LED TIR lenses. The mainstream is TIR lens type, however, refractive lens is common, such as streetlight lenses that is a kind of freeform lenses.

Non-imaging Optics - Ultra-Precision optics

In the field of so-called ultra-precision optics, it uses diamond turning machines to replace CNC one. The stroke of ultra-precision machine can achieve level of 50 nanometers, while the surface finish can reach the SPI A1 level without polishing. This process is applied to flash lens, TV lenses, and imaging optics lenses.

Near-Field and Far-Field

Generally, near-field optical design means an optical lens is at a distance of 5 to 10 times the size of light emitter used in the optical simulation model. For near-field cases, the imaging properties of optics influence visually the energy presentation. Examples for this category are IR lens design, LED package optics, and Powell lenses. For far-field optical, on the other hand, optical lens is far-away the light emitter, maybe larger than 10 times size of the light emitter or more. In this case, the influence of near-field characteristics disappears, and the accuracy of the simulation results of optical model will be much better.

We have prolongedly invested in R&D resources in the non-imaging optical fields over a decade. We can quickly and accurately implement optical design, development and production, while assisting customers in completing projects with competitive processing, molds and forming.
