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.

Sapphire window retains its high strength at high temperatures, has good thermal properties and excellent transparency. It is chemically resistant to common acids and alkali at temperatures up to 1000 °C as well as to HF below 300 °C. These properties encourage its wide use in hostile environments where optical transmission in the range from the vacuum ultraviolet to the near infrared is required.

HG Optronics.,INC. can provide Metal Coated Mirror，Dielectric Coated Mirror and Dichroic Mirror which are made of substrate such as BK7, Optical glass, Fused Silica, CaF2 and so on.  

HGO have advanced coating machines which can meet endusers’different application requirement. We can very high laser induced damaged threshold coating with IAD, EB and IBS coating techniques , also Cr-Au, Aluminum and silver mental coating can also be available in HGO. Customers are very welcome to contact with us for further information.

YbYAG crystal is more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 0.94 μm laser output. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications.

  LiNbO3 is widely used as electro-optic modulators and Q-switches for Nd:YAG, Nd:YLF and Ti:Sapphire lasers as well as modulators for fiber optics.  

HGO grows BBO Nonlinear crystals using flux technology. BBO crystal transparency ranges from 188 nm to 5,2 µm, which includes reasonable transparency from 3-5,2 µm for few tens µm thick crystals, while their phase-matchable range spans almost over the entire transparency range. Combined with other magnificent properties of BBO, it is favorable for numerous nonlinear parametric applications. It is worth to mention that BBO crystals have the highest nonlinearity in the UV range out of all common nonlinear crystals.

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.
