Klaran UVC LEDs

Crystal IS have added Klaran to their high performance UVC LED range, aimed at advancing disinfection solutions for healthcare.

Ultraviolet (UV) disinfection has become a reliable and viable alternative to chemical disinfection methods due to the increased awareness of chemical-resistant microbes and the presence of harmful by-products. High power Klaran UVC LEDs are characterized by their unique germicidal output power, or Po. Tuned to maximum DNA absorption of harmful pathogens, these devices are highly effective at disrupting their ability to reproduce, continuing the fight against the spread of costly HAIs. Unlike mercury UV lamps that are typically long cylindrical bulbs encased in a fragile quartz tube, Klaran solid-state semiconductor devices offer an industry-standard 3.5 mm x 3.5 mm footprint that provides maximum design flexibility for engineers.

Klaran offers an ideal solution for manufacturers who wish to incorporate UVC technology into their Point of Use (POU) consumer products, or manufacturers of lab water equipment who are expected to satisfy a range of industry standards. Klaran UVC LEDs have been proven to meet dosage requirements that satisfy NSF55 Class A requirements in certain reactor designs.  Crystal IS is an industry leader in AlN crystal growth, and their proprietary crystal growth technology delivers the most reliable UVC LEDs optimized for germicidal irradiation on the market today.


    Powerful UVC germicidal output of 250 nm - 280 nm capable of deactivating a wide array of bacteria and microorganisms.
    Small, robust 3.5 mm x 3.5 mm footprint affords maximum design flexibility
    Back side thermal extraction safe for use with heat sensitive substrates
    Directional emission enables accurate delivery of UVC energy
    Accepts solder reflow processing to accommodate high volume production rate


    Crystal growth derived from patented native Aluminum Nitride substrate technology
    Capable of running off portable DC power source
    Accepts drive current up to 400 mA
    Available in power bins from 15 mW to 30 mW
    Viewing angle of 105 degrees

The BAC201 is a new fibre optic Raman probe from BWTek, designed to analyze samples in hard-to-reach places.

The probe end is constructed from a single 200 μm core laser fibre surrounded by nine 200 μm core return fibres, all encased in a 3.0 mm OD stainless steel needle tube. The probe tip is sealed with a fused silica ball lens, which allows for high throughput and easy cleaning. The optical elements inside the needle are permanently fixed in alignment, with no possibility of movement due to impact or vibrations.

The probe can be used for immersion or direct contact measurements, and can access difficult to reach spots eg inside small cavities, tissues, and miniature reactors. The recommendation is to avoid strong acids, bases, or other chemicals that might attack fused silica or stainless steel.

Key parameters:

Probe Tip Diameter: 3.0 mm
Probe Tip Length: 15.6 cm
Overall Length: 1.5 m
Working temperature range: -50°C to +100°C
Raman Excitation Wavelength: BAC201-785 (785nm)
Rayleigh Rejection: >>OD3
Spectral Cut-off: 600 cm-1

CIPRM balanced optical receiver

In the CIPRM-1 series balanced optical receiver, Excelitas has incorporated the best features of high performance InGaAs photodiodes and a low noise, high gain transimpedance amplifier to offer a practical solution to detect small changes above the interfering noise floor of an incoming signal. The advantage is that the common optical noise is cancelled out.

This coherent InGaAs PIN balanced receiver module incorporates two low-noise photodiodes with well-matched responsivity in order to ensure a high common mode rejection ratio (CMRR). It has two single mode fibre optic inputs, an RF output, electrical supply inputs, and two photo-current monitor outputs. The CIPRM modules come in a robust casing with flange mounting holes for securing the module to working surfaces or platforms. Combined with a wide operating temperature range, the CIPRM can work in some of the toughest and harshest environments.
Key Features include:

•Spectral range - 800 - 1650nm
•200MHz bandwidth
•High performance InGaAs photodiode and TIA
•Matching responsivity
•Photo-current monitor outputs
•Rugged and robust
•RoHS compliant


•Optical delay measurement
•Heterodyne detection
•Optical coherent tomography
•Ultra low signal detection

Access Laser helps to measure Gravitational Waves

Precision CO2 lasers made by Pacer supplier Access Laser have played a part in the recently announced confirmation of the existence of gravitational waves.

Access Laser has been collaborating with the Laser Interferometer Gravitational-Wave Observatory (LIGO) for more than 10 years. Several models of the company's stabilized lasers have been used by LIGO in the US and the European Gravitational Observatory.

Special design efforts have been made to meet the LIGO's ever-increasing demand to achieve high-stability, low-noise, and extremely sensitive operation. An auxiliary system uses a CO2 laser to heat the mirrors in a manner precise enough to counteract the shape-changes that occur as a result of heating from LIGO’s main laser. The CO2 laser that is used is an RF excited Merit-S Model CO2 laser manufactured by Access Laser Company. The laser was chosen because of its proven ability to not line hop over extended periods.

More details on Access Laser CO2 lasers can be found on our product page.
