Aspherical lens Aspherical lens is a single optical component with one or two aspheric surfaces. An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspherical elements eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design. Our aspheric lenses are made by grinding & polishing. So they are more precise than traditional mould pressed. And also the tooling cost for grinding & polishign would be cheap and small quantity order would be accept. We can offer Precision Polished Aspheric Lenses Aspheric Condenser Lenses Aspheric Cylindrical lenses ect.

Micro Light-guide Prism Micro light-guide prism are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image's handedness is changed to the opposite sense. Dove prisms have an interesting property - when they are rotated along their longitudinal axis, the transmitted image rotates at twice the rate of the prism. It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean. Another application is used as a retroreflector. For this application it performs as a right-angle prism. Used in Interferometry, Astronomy and Pattern Recognition.

IR Cut off Filters Worldhawk can providea precision filters for many applications, including bandpass interference filter, Cut off filters, UV bandpass filter, Narrow bandpass filter, ND filter, Negative Filter or Notch filters, dichroic, color substrate. Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries. Custom filters are available for both large manufacturing needs and in prototype volumes. Contact us for more information or to arrange a quote. Cut Off filters - Dichroic Filter - Longpass Edge Filters ( Long pass Filters) - Shortpass Edge Filters ( short pass Filters) - IR Cut Filters ( IR-CUT Filter) - UV-IR Cut Off Filters Longpass Filters transmit wavelengths greater than the cut-on wavelength, while Shortpass Filters transmit wave- lengths shorter than the cut-off wavelength. Dichroic filters perform the same function, while guaranteeing that the rejected wavelengths are reflected. Any of these filters can be designed for 0 or 45 angle of incidence. Edge and Di- chroic Filters are commonly used in Fluorescence instrumentation, Heat Rejection Applications, and as Color Filters. While somewhat angle sensitive, they are more forgiving than bandpass interference filters. UV IR Cut is a specialized filters that has the ability to cut both UV rays below 400nm and IR rays above 680mn leaving just the light rays in the visible spectrum passing through the filter and into the camera.This filter is used on a digital camera and the video 350-405nm:Tavg<10% 415±10nm:T=50% 430-630nm:T>85%, Tavg>90% 650±10nm:T=50% 700-1100nm:T<3%
