Single-mode VCSELs in a hermetically sealed TO housing allow easy handling of the laser diode and are suitable for operation in demanding ambient conditions. In addition, a burn-in test is made possible; an integrated Zener diode reduces the electrostatic discharge (ESD) of the laser components. Various wavelengths are available, from 760 nm to 940 nm.
The single-mode VCSEL platform is designed for extremely low power consumption and high output power. The polarisation lock achieves polarisation control without compromising power efficiency.
The TO package around the VCSEL hermetically seals the electronics inside the housing. No damage occurs even in demanding ambient conditions.
The TO housing with integrated TEC is for applications that require a large temperature window or spectral stabilisation of the laser diode. This allows the laser temperature to be precisely controlled.
Product variants with wavelengths from 760 nm to 940 nm are available to suit the application requirements.
Industrial encoder for the most precise positioning
Single-mode VCSELs are perfectly suited to use in optical encoders as they have a Gaussian-shaped beam profile and long coherence length. In addition, the hermetically sealed TO housing is perfectly suited for use in industrial environments.
Industrial speed and distance sensors
TO housings are robust enough for use in industrial environments. They are used as speed and distance sensors for various materials, including sensitive materials like fabrics.
Oxygen sensors (TDLAS)
Single-mode VCSELs in TO housing with TEC are excellent for TDLAS applications (Tunable Diode Laser Absorption Spectroscopy).
Product variants on request with the following characteristics:
TO housings are available with and without temperature control (TO housing with TEC and thermistor).
Various wavelength configurations are available as 740 nm, 760 nm or 850 nm.
Polarisation-stable single-mode VCSELs with monolithically integrated photodiodes are available.
