Double Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. Double-Convex Lenses are used in a range of industries or applications. HG OPTRONICS offers Double Convex lenses with a variety of coating options.

The Positive Meniscus Lenses are a convex-concave lens, but it is thicker at the center than at the edges. They are felt polished and are used universally in the ophthalmic industry where convention dictates that lens power be specified in Diopters. The Negative Meniscus Lenses are a convex-concave lens, but it is thinner at the center than at the edges. Otherwise description is similar to Plano Concave lenses.

Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. Achromatic Lenses, which are often designed by either cementing two elements together or mounting the two elements in a housing, create smaller spot sizes than comparable singlet lenses.

Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. HG OPTRONICS can provide the size from Φ1～Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to customers upon request.

Longpass filters are ideal for a variety of applications, such as gas monitoring, temperature, sensing, thermal imaging and motion sensing, etc. Longpass filters block shorter wavelengths and transmit longer wavelengths. Blocking can be from reflectance, absorption or a combination. Transmission in the pass band can be enhanced with an antireflection coating on the second surface.

The dichroic mirror is a mirror with significantly different reflection or transmission properties at two different wavelengths, it’s characterized by almost complete transmission of light at certain wavelengths and almost complete reflection of light at other wavelengths. It can be widely used in Laser technology applications.
