1. SZR Series Visible (VIS) Dome Lens

Optical domes can be seen as a kind of optical windows. It has no optical effect on optical path. Optical domes are ideal for split level and underrater work, meteorology and defense applications, aerospace and military application. BK7 is ideal for underwater camera domes, marine domes and any other visible to near infrared lead applications where clarity and strength is essential. We also offer precision domes from infrared material for much longer wavelength

  • Maximum Diameter can reach 350 mm
  • Surface Accuracy can reach λ/10

2. SZR Series Infrared (IR) Dome Lens

We offer infrared optical domes from a variety of substrate materials:

  • Sapphire
  • Fused Silica
  • Calcium Fluoride (CaF2)
  • Magnesium Fluoride (MgF2)
  • Zinc Sulfide (ZnS), Zinc Selenide (ZnSe)
  • Silicon (Si)
  • Germanium (Ge)

Sapphire is ideal for both ultra-violet (UV) and MWIR (3-5micro) band, MgF2 are good for MWIR band, ZnSe and Germanium are good choice for 3μm to 12μm domes covers both MWIR and LWIR region.

3. SZR Series Ultraviolet (UV) Dome Lens

Most optical glasses can effectively transmit visible and near-infrared light. However, in the near ultraviolet region, most glass absorbs light to some extent. If the optical system must transmit ultraviolet light, the most common materials are fused silica and fused silica. Some heavy flint optical glasses have a low transmittance in the dark blue wavelength range and have a slightly yellow appearance.

One of the characteristics of quartz glass is that it has high light transmittance for ultraviolet, visible, and infrared rays. Quartz glass made from ultra-pure silicon dioxide (SiO2) as raw material has a total metal element content of only 1% × 10-6, therefore the UV transmittance is the highest, especially for shortwave UV; The wavelength of 180nm has a transmittance of up to 80%, and the wavelength of 190nm has a transmittance of up to 90%, making it an ideal ultraviolet material.

  • Maximum Diameter can reach 350 mm
  • Surface Accuracy can reach λ/10

4. SZR Series Large Diameter Optical Domes

We focus on the research and development and mass production of large-diameter optical domes. Our company uses leading dome processing technology combined with patented independently developed molds to solve the common problems of deformation and uneven size caused by uneven shrinkage of various parts of the glass dome due to temperature differences between the top and bottom of the glass during the processing. This technology solves the problem of difficulty in forming large size infrared glass, improves the yield rate of large diameter glass dome lens, and expands the application of products. The large diameter infrared glass optical domes produced by our company are currently used in some models of scientific research institutes of aerospace and weapons. The product quality is stable and has received praise and trust from customers.

  • Maximum Diameter can reach 350 mm
  • Surface Accuracy can reach λ/10

5. SZR Series Irregular Cut Dome Lens

We process uncommon irregular-shaped optical domes according to customer's requirements. Using precision cutting machines, the edges of the dome can be cut into arcs according to the customer's design to suit your specific optical system. Optical domes can be seen as a kind of optical windows. It has no optical effect on optical path. Optical Domes are ideal for split level and underwater work, meteorology and defense applications, aerospace and military application.

N-BK7 is ideal for underwater camera domes, marine domes and any other visible to near infrared lead applications where clarity and strength is essential. We also offer precision domes from infrared material for much longer wavelength.
