Precise, accurate and stable LEDs for environmental monitoring

AP Technologies works with customers throughout the UK in environmental monitoring industries, supplying COTS and custom-engineered LED components and instruments. Their products include sophisticated and precise LED components; as different pollutants absorb and fluoresce at specific wavelengths; appropriate LED selection is crucial for accurate detection. AP Technologies offers robustly packaged LEDs from UVC at 235nm though visible and into the NIR-MWIR. Multi-wavelength options are also available.

LEDs should have consistent spectral characteristics and stable output over time to maintain accuracy and ensure reliable, repeatable measurements. AP Technologies’ LED products are renowned for their consistency of performance and long product lifetime. In addition, systems can allow for the integration of a monitor photodiode to constantly monitor and ensure a stable output throughout the product's lifetime.

AP Technologies also offer NewDEL™ fibre-coupled LED instrument light sources featuring built-in drivers and microcontrollers and offering flexibility and control over parameters such as pulse duration and pulse width modulation. With high brightness and optimised output quality, these products offer both stability and energy efficiency.

They can also provide a broad range of industry-standard surface mount or though-hole TO-style or moulded packages as well as custom configurations. In addition AP Technologies also provides LED light source instruments with both standard and custom options available.
