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.

AR Coated Negative Achromatic Lens
Broadband AR Coated Achromatic Lenses(Doublet 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.

NdYAG Crystal for solid-state laser
Nd:YAG crystals Neodymium Doped Yttrium Aluminum Garnet

Nd:YAG is the earliest and most famous laser host crystal. Since it combines great advantages in many basic properties,Nd:YAG is the ubiquitous presence for near-infrared solid-state lasers and their frequency-doubler, tripler, and higher order multiplier. It is widely used in industrial, medical, military and scientific fields.. Nd:YAG crystals are wildly used in all types of solid-state laser systems-frequency-doubled continuous wave, high-energy Q-switched, and so forth.Its good fluorescent lifetime thermal conductivity and physical strengths makes it suitable for high power lamp pumped laser.

Nd:GdVO4 Crystal Neodymium Doped Gadolinium Orthovanadate

Nd:GdVO4, is a promising material for diode pumped lasers. Similar to the more well-known Nd:YVO4 crystal, Nd:GdVO4 crystal also exhibits high gain, low threshold, and high absorption coefficients at pumping wavelengths. Nd:GdVO4 has the additional advantage over Nd:YVO4 of a much higher thermal conductivity. For CW lasing at 1.06 um and 1.34 um and intracavity doubling with KTP and LBO, the gadolinium vanadate have produced a higher slope efficiency or optical conversion than Nd:YVO4.
