Hydrogen fluoride detection with 2476 nm DFB laser diodes
Hydrogen fluoride (HF) is a very poisonous gas. Therefore, it is very important to detect it in small traces. The laser manufacturer Norcada from Canada, represented in Europe by EQ Photonics, introduced a DFB laser diode with emission wavelength 1278 nm which is optimized for HF detection. The laser diode is assembled in a TO39 package with TEC and thermistor. The typical optical power is 10 mW. A variant with collimation lens is available as well. Here you get a beam diameter below 4 mm in distance of 2 meters. Further available for HF detection stay the 2476 nm DFB laser diodes without or with lens.
1550nm Ultra-Narrow Linewidth (3 kHz) Laser for OTDR
The DenseLight BF21-“MicroPhotonic MatchBox”-Series consists of highly integrated laser modules with a small form factor of only 88x100x22mm. The narrow linewidth emission of less than 3 kHz (optional up to 100 kHz) enables high precision optical metrology & instrumentation such as temperature (DTS, B-ODTR), moisture, stress or elongation measurements.
The BF21 is complete with a DenseLight diode laser, integrated laser driver & temperature controller.

Denselight DFB lasers are available in fiber-pigtailed versions as well as lensed TO packages. The new DS-DF6101T2C-1653.7 comes in a cost-effective and compact TO60-can including cooling. Its center wavelength of 1653.7nm and an output power of 10mW allows the design of accurate Methane sensors. Lasers with center wavelength of 1512nm for Ammonia detection are available on request.

VCSEL-specific spectrometers
OtO Photonics is launching the Merak Series (MR) spectrometers, which adopt a transmission grating and a fully transmissive Czerny-Turner optical design to deliver high resolution, high sensitivity, low dispersion, and high-speed spectrum response. This series also features an improved integrated body and built-in LED indicators. It employs patented alignment mechanism to deliver optimum (0.1 nm) optical resolution to address the needs of high-resolution and high-sensitivity measurements. The MR series has a wavelength range of 830 - 970 nm, with a resolution <0.1 nm. Therefore, it is an ideal solution for VCSEL characterisation.Dubhe (DB) spectrometers for optical coherence tomography
Dubhe (DB-series) spectrometers are designed for the high-resolution, high-sensitivity measurements required by optical coherence tomography (OCT). This new series features a transmissive optical design with an improved integrated body, employing patented alignment mechanism to deliver ultra-high (0.04 nm) optical resolution in the range from 800 - 880nm. It is available in two versions with different CMOS camera max line rates: 80 kHz or 20 kHz. The DB series uses a transmission grating and a fully transmissive Czerny-Turner optical design to deliver high optical resolution, high sensitivity, low dispersion, and high-speed spectrum response.
Phekda-series ultra-high-resolution compact spectrometers
OtO Photonics releases the Phekda (PD-series) ultra-high-resolution general-purpose micro-spectrometers, featuring a T-R-T (transmissive-reflective-transmissive) optical design with resolutions up to 0.1nm to address the needs of ultra-high-resolution measurements under narrow wavelength ranges. The innovative T-R-T design provides the flexibility of highly customizable wavelength ranges. You can choose the range in the VIS or NIR (within limits of 400 - 1000 nm or 900 - 1700 nm) to fit the specific needs. The PD-series is used in various applications such as optical coherence tomography, laser induced breakdown spectroscopy (LIBS), VCSEL source characterization, and Raman spectroscopy.
