Lab starter kits UV-enhanced silicon photodiodes
OSI Optoelectronics (OSIO) now offers UV- enhanced planar diffused silicon photodiodes specially designed for low-light-level detection in the ultraviolet spectral range. The product series includes the UVD planar diffused and UVE planar diffused IR suppressed devices, both featuring excellent UV response. The UVD and UVE photodiodes exhibit significant advantages, including lower capacitance and higher response times. OSI Optoelectronics’ UVD photodiodes
High-power red laser diodes
ProPhotonix has added two high-power red laser diodes from Ushio to its range. The 637nm HL63283HD delivers an output
power of 1.2W in continuous wave and up to 1.5W when pulsed. This powerful red laser diode is ideally suited for use in laser projectors, show lasers and as a light source in optical equipment.
The HL63290HD is a 638nm laser diode Picowatt photoreceiver series
Femto Messtechnik has released a picowatt photoreceiver from 320 to 1,060nm and 900 to 1,700nm. The new picowatt photoreceiver series PWPR-2K with switchable gain (109 V/A, 1010 V/A) and a bandwidth from DC to 2kHz is the ideal choice for CW measurements, time resolved signal acquisitions and highly sensitive modulated measurements, in addition to precise and fast CW measurements. The combination with lock-in amplifiers
results in ultra-sensitive measurement systems being almost immune to disturbances from external sources. In this way the PWPR-2K can easily detect optical powers from about 100fW up to 10nW. Offering both free space and fibre coupled
formats, both Si and InGaAs PIN diode options are available. Carefully designed EMC housings include fixing holes for both

laboratory and OEM constructions. The output voltage range is up to +10V, with an offset adjustment by a potentiometer. The photoreceiver includes output short-
circuit protection. As is standard for all Femto products, a power supply with ±15V via 3-pin Lemo socket, PS-15, is supplied separately.

peak at 970nm. The UVE devices peak at 720nm and suppress the near-infrared, making them particularly useful in applications where blocking the NIR spectral region is required. Both products can be biased for lower capacitance, wider dynamic range, and high speed response times. Alternatively, the UVD and UVE series may be operated in the photovoltaic (unbiased) mode for situations that require low drift with temperature variations. Available in varying sizes and footprints.

producing output powers up to 2.5W when pulsed. In continuous wave, the laser provides 2.2W of output power, making it well suited to laser projection applications. This higher power red laser diode is also suitable for those optical equipment applications requiring power levels above 2W. Both diodes are packaged in compact 9mm
cans, providing excellent heat dissipation.

Edmund Optics has introduced three new kits designed for starting a brand new lab and keeping it stocked. The Lab Starter Kits are available in English and metric-based mounting versions and feature essential products useful for any lab, from optics to detectors to cleaning and tools. The Lab Essentials Kit includes many components typically consumed in an optical lab. Both kits are RoHS compliant. The Lab Starter Kits provide 255 individual
parts including a range of lenses, filters, and prisms mainly suited for the visible spectrum. Additional optomechanics and tools, such
as stages, mounts, clamps, wrenches, hex and screw drivers, as well as adapters that are compatible with the included optics, also come in the kit.
The Lab Essentials Kit provides many items
that are typically consumed or lost in an optical lab. It includes a wide variety of products including cleaning supplies, tools, and basic mounting components.

Collimated beam shaper module
Holo/Or’s collimated beam shaper module is a tailored solution for applications requiring an extended working distance range or long depth of focus. With this module, the uniform-intensity beam is maintained with high fidelity, power uniformity, and constant size/shape over an extended working distance range. The shape is well-defined with sharp edges, and it can be round, square, rectangular, elliptical, line, or any other shape or dimension. For multi-mode sources, the collimated
homogeniser module is Holo/Or’s tailored solution for applications requiring a long working distance range. The collimated homogeniser is the natural complement for the firm’s standard diffractive homogenisers, which give a shaped intensity beam at a unique specified working distance. The collimated homogeniser is a good solution for applications such as industrial surface treatment, where the working surface is uneven or located at varying distances from the laser delivery system.
