Core Pain Points We Solve Across All Dome Applications
Single dome structure cannot match diverse installation and field-of-view demands
Improper raw material selection causes light failure under different spectrum environment
Abrasion, salt fog, high pressure and thermal shock lead to frequent lens damage outdoors
Few manufacturers own full-form dome processing capacity for all industrial scenarios

Optical Substrate Material Selection Guide
Select proper raw material based on your working spectrum, environment and equipment application
| Optical Material | Key Performance Features | Suitable Dome Types | Working Spectrum | Limitations & Notes |
|---|---|---|---|---|
| Single Crystal Sapphire | Mohs 9 high hardness, salt corrosion resistance, thermal shock stable, broadband transmission | All 6 types dome | UV ~ Mid IR | Higher cost; best choice for harsh environment |
| BK7 / H-K9L Optical Glass | Low cost, easy precision polishing, stable visible light performance | ROV shallow water, UAV visible camera, marine shore monitoring, flanged dome, hyper hemispherical dome | Visible & Near IR | Cannot pass MWIR/LWIR; Not recommended for deep sea long-term immersion |
| ZnS (Zinc Sulfide) | Excellent mid & long infrared transmittance | MWIR LWIR thermal imaging IR dome, hyper hemispherical panoramic IR dome | Visible ~ LWIR | Not ideal for long-duration salt fog environment |
| ZnSe (Zinc Selenide) | Low absorption in long wave infrared, ideal for thermal camera | MWIR LWIR thermal imaging IR dome | NIR ~ LWIR | Soft surface, need protective coating; higher price |
| Germanium (Ge) | High transmittance for long wave infrared | MWIR LWIR thermal imaging IR dome | MWIR / LWIR | Strong absorption under high temperature, only for thermal system |
Reminder: We support customized single-layer & broadband BBAR anti-reflection coating matched with each substrate. Send your spectrum requirement for free material recommendation.

Frequently Asked Questions For Combined Series Optical Dome
Q1: Can BK7/H-K9L glass be used on infrared thermal imaging dome?
A: Not available. BK7 only transmits visible and near-infrared light, light will be completely blocked under MWIR/LWIR waveband, infrared dome must adopt ZnS,ZnSe or Germanium crystal.
Q2: When should we pick sapphire instead of BK7 glass?
A: Choose sapphire for deep-sea long-term soaking, high altitude airborne harsh environment,anti-salt fog requirement and dual-band visible+IR imaging projects.
Q3: Do you support switching dome structure after prototype confirmation?
A: We can adjust six existing mature outlines for secondary modification according to customer installation structure, extra mold cost only for brand-new customized radian.
Q4: Can one dome realize both day visible shooting and night thermal imaging?
A: Yes,select sapphire broadband substrate plus BBAR dual-band anti-reflection coating to achieve dual-spectrum synchronous imaging.
Q5: Can we order mixed-type dome bulk procurement in one order?
A: Accept mixed SKU consolidated order of six dome types, unified delivery to reduce client multiple purchasing cost.
