Product Description
LWIR Lenses
Longwave Infrared (LWIR) lens is typically uncooled and therefore, has less sensitivity. It allows the user to see through dust or smoke, which makes them particularly valuable in certain environments and applications. The field of view of a lens depends mainly on the focal length and the detector size. Customization is available for this product. Let us know your specifications in the RFQ form.
What is Infrared Optics? An Introduction to Infrared Optics
1. What is Infrared Optics? Infrared optics are used to collect, focus or collimate light in the near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MWIR) or long-wave infrared (LWIR) spectra. The infrared spectrum falls in 700 - 16000nm wavelengths and each respective spectra are ranged as:
NIR 700 - 900nm
SWIR 900 - 2300nm
MWIR 3000 - 5000nm
LWIR 8000 - 14000nm
2. Short-Wave Infrared (SWIR)
SWIR system covers from 0.9μm-3μm spectrum range. The optics material needs to transmit visible and infrared light and does need a light source such as the sun, moon, stars, etc. It is being utilized in numerous applications such as spectroscopy for sorting, moisture detection, thermal imaging (used for glass and plastic objects), and imaging - night vision and imaging lasers.
3. Mid-Wave Infrared (MWIR)
MWIR system covers a 3-5μm spectrum range and is typically a cooled system. Thus, it is less affected by humidity compared to the LWIR system for most target ranges, which is suitable for applications like coastal surveillance, vessel traffic surveillance, or harbor protection. Since the primary goal is to obtain high-quality images rather than focusing on temperature measurements and mobility. The images below indicate that MWIR image is sharper and has high thermal contrast compared to LWIR image.
4. Long-Wave Infrared (LWIR)
LWIR system operates from a 7-14μm spectrum range. However, most LWIR camera effectively covers from 8-12μm. LWIR system is commonly known as "thermal imaging" since it detects heat signatures emitting from an object and does not require illumination to form an image. Yes, our range of LWIR lenses also plays an important role during the COVID-19 pandemic. The thermal imaging capabilities of the LWIR system have made it an attractive key component for a growing number of security, surveillance, scientific, and industrial applications.
5. Functionality Categorization
Generally, infrared optics are categorized into SWIR, MWIR, and LWIR in terms of the wavelength spectrum. However, it is also sub-categorized into how it is being designed corresponding to its functionality such as:
Athermal Lens An optical system is athermalized if its critical performance parameters such as modulation transfer function, back focal length and effective focal length, etc. do not change appreciably over the operating temperature range.
Zoom Lens An optical system that covers narrow and wide FOV continuously.
Dual FOV Lens An optical system that provides an option to switch from wide to narrow FOV distinctively.
Dual-Band Lens
An optical system that covers both MWIR and LWIR spectrum range.
