Non-Radiometric Thermal Camera Germanium Glass Window for IP67 – Complete FAQ Guide

When designing a sealed enclosure for a thermal module, selecting the correct non-radiometric thermal camera germanium glass window for IP67 protection is critical. Incorrect material choice can completely block infrared transmission and degrade system performance.

This FAQ explains radiometric capability and the correct window material for IP67 housing integration.

1) Is the thermal camera radiometric?

Q: Is your thermal camera radiometric?

一個: 沒有. Our module is a non-radiometric thermal camera.

It is a passive infrared imaging sensor that detects long-wave infrared (長波紅外線) radiation and generates thermal images. 然而, it does 不是 provide per-pixel temperature measurement or absolute temperature data output.

This type of non-radiometric thermal camera is ideal for:

• 無人機有效載荷
• Night vision systems
• Security surveillance
• Target detection
• 工業監控

If your application requires temperature measurement and thermal analysis, a radiometric version would be required instead.

2) Why is a Germanium Glass Window Required for IP67?

When designing a sealed enclosure, you must use a non-radiometric thermal camera germanium glass window for IP67 protection.

Thermal cameras typically operate in the 8–14 μm LWIR wavelength range. Standard optical glass or tempered glass used for visible light will block infrared radiation and make the thermal image unusable.

Recommended Material: Germanium (Ge)

Germanium is widely used in thermal imaging systems because:

• High transmission in the 8–14 μm infrared spectrum
• Stable optical performance
• Good mechanical strength
• Suitable for sealed IP67 outdoor environments

3) Important Design Notes for IP67 Housing

When integrating a non-radiometric thermal camera germanium glass window for IP67, 考慮以下因素:

• Use AR coating designed specifically for 8–14 μm LWIR (not visible-light AR coating).
• Select proper window thickness (commonly 1–3 mm depending on size and pressure requirements).
• Ensure waterproof sealing to prevent moisture ingress.
• Prevent internal condensation using proper ventilation or desiccant solutions.

Incorrect window material selection is one of the most common causes of poor thermal image performance.

結論

If you are designing a sealed enclosure, always choose the correct non-radiometric thermal camera germanium glass window for IP67 應用. Standard glass will not work for LWIR systems.
