These LEDs emit light at wavelengths that can excite specific compounds, enabling the detection of contaminants in water samples.
Technology of Biological Instrument LEDs
The technology behind Biological Instrument LEDs is based on the principles of semiconductor physics. These LEDs are typically made from gallium nitride (GaN), a wide-bandgap semiconductor material that can emit light at a wide range of wavelengths. The key components of a Biological Instrument LED include:
1.
Active Region: The active region is the core of the LED, where the semiconductor material emits light. In Biological Instrument LEDs, this region is engineered to emit light at specific wavelengths by incorporating quantum wells or other optical structures.
2.
Contacts: The contacts are used to connect the LED to an electrical circuit. They are typically made of metals such as gold or aluminum, which have high electrical conductivity and low light absorption.
3.
Substrate: The substrate is the base material on which the LED is grown. In the case of GaN-based LEDs, the substrate is typically sapphire or silicon carbide, which have high thermal conductivity and mechanical strength.
