What is the difference between MWIR and LWIR?

Infrared Imaging White Paper As shown in Figure 1, photovoltaic infrared detectors (such as MCT and InSb) are currently available for imaging is several distinct bands, including SW/MWIR (1.5-5.0µm), MWIR (3- 5µm), LWIR (7.5-9.5µm) and VLWIR (7.5-11µm).

What is SWIR and MWIR?

The three wavelengths are: Short Wavelength Infrared (SWIR), Medium Wavelength Infrared (MWIR), and Long Wavelength Infrared (LWIR). All Thermal imaging devices operating on the infrared wavelength are, ‘imagers’ that we commonly refer to as ‘cameras’, however they are actually sensors that can detect radiated heat.

What is Mwir?

Medium-wave infrared (MWIR) is a subdivision of the IR band of the electromagnetic spectrum, which captures infrared energy in the 3 to 5 micrometer medium-wave infrared (LWIR) spectrum.

How is Lwir calculated?

Formula: Recordable cases x 200,000 / Hours worked. Lost Workday Case Incidence Rate (LWIR): Number of days lost due to nonfatal injuries and/or work-related illnesses per 100 full-time employees.

What is Lwir in safety?

Lost Workday Case Incidence Rate (LWIR): Number of days lost due to nonfatal injuries and/or work-related illnesses per 100 full-time employees.

What is INSB detector?

High-speed, low-noise infrared detectors capable of detecting infrared light up to approximately 3.5 μm.

How is OSHA Lwir calculated?

The LWR formula is defined as the total number of workdays lost multiplied by 200,000, divided by the total number of hours worked by all employees within a given period.

Why InSb is a semiconductor?

Indium antimonide (InSb) has the smallest band gap of any of the III–V semiconductors (E o∼0.18 eV at 300 K, Ref. [1]). InSb is, thus, an interesting semiconductor for use in long-wavelength optoelectronic device applications. Its relatively high electron mobility (μn∼7×104 cm2/V-s at 300 K, Ref.

What is the difference between TRIR and Ltir?

All incidents which result in occupational injury will be recorded using Total Case Incident Rate (TCIR) or Total Recordable Incident Rate (TRIR). Only those which result in more than one day away from work (LTIs) are recorded using LTIR.
