Optical Replication Process

OPCO (Fitchburg, MA) offers a replication process that reproduces complex optics. The process transfers the profile of a precision optical surface from a master, creating an exact duplicate on a variety of substrates. The replicated optics are less expensive and in many cases lighter than the master. This process can be used to produce a range of both ruled and holographic diffraction gratings, reflective and transmission holographic optical elements, and dual wavelength gratings, as well as plano and conic sections. Substrate materials include glass, silicon carbide, ceramic, and metals such as beryllium, aluminum, titanium, stainless steel, and others. Diffraction gratings are produced in sizes up to 110mm × 110mm with groove densities from 40 g/mm to 3,600 g/mm, with available wavelengths from the deep UV to the far IR.

Miniature Spectrometers

The XR-Series of miniature spectrometers from Ocean Optics (Dunedin, FL) covers all wavelengths from ~200 - 1050 nm and are available for USB2000+, JAZEL2000, and USB4000. The XR-2 grafting option provides broad UVNIR coverage with 500 lines/mm density without increasing the system footprint. They deliver an optical resolution of ~2.0 nm (FWHM) and are suitable for setups where both UV-VIS and VIS-NIR measurements are needed. They are also suitable for measurement of samples with response across the entire wavelength range, including solar irradiance, atomic emission line measurement, and some plasma applications.

Optical Spectrometer

Mcpherson (Chelmsford, MA) has developed a 248/130 grazing incidence wavelength dispersive optical spectrometer that analyzes spectral light in the ~1 to 300 nm wavelength region (4 to ~1200 eV). It is useful for the vacuum ultraviolet as well as the extreme and soft X-ray wavelength region. Using direct detection CCDs, gated image intensifiers, or fast channel electron multipliers for detection, the instruments are vacuum leak checked and calibrated with respect to wavelength. Vacuum ultraviolet spectroscopy accessories, including various detector systems and wavelength calibration sources, are available from

Non-Contact Laser Shutters

FlexSorb™ laser shutters from nmLaser Products (San Jose, CA) feature a high damage threshold, small size, and quiet operation. The moving part is a low-mass, flexible, ferromagnetic cantilever membrane that is moved in and out of the beam by noncontact electromagnetic techniques. The shutters are immersion cleaning compatible and can be used for clean room type applications. They are designed for 24V type circuits with a timed impulse to open and a lower voltage for long-term hold. Aperture sizes range from 3mm to 14mm. They feature switching speeds from under 10 msec to 50 msec, and exhibit low backscatter from DUV through FIR wavelengths.

Glass-Glass Photovoltaic Modules

Silicon Energy (Arlington, WA) and DuPont Photovoltaic Solutions (Wilmington, DE) have introduced glass-glass polycrystalline silicon (cSi) photovoltaic (PV) power-generating modules made with DuPont™ PV5300 series ionomer-based encapsulant for added module strength and durability. Two 60-mil layers of the encapsulant surround silicon wafers to add high-transmittance tempered glass and increased flexural strength over traditional modules. The encapsulant is also resistant to moisture intrusion.

RGB Laser Driver

Maxim Integrated Products (Sunnyvale, CA) has introduced the MAX3600, a 3-channel RGB laser driver that enables integration of high-resolution pico projectors into small-form-factor applications. Fabricated using Maxim’s BiCMOS process, the device achieves switching times of s generate billions of colors and contrast ratios of 5000:1 and higher, while consuming 75% less real estate and 30% less power than discrete designs, making it suitable for battery-operated devices. Packaged in a 5mm × 5mm, 40-pin TQFN, the MAX3600 operates over temperatures ranging from 0 °C to +70 °C.

Boreoscope Camera

The FSC2 boreoscope camera from Schoelly Imaging (Worcester, MA) features an integrated LED light at the camera head, eliminating the need for light cables. The small CCU features auto white balance, variable brightness control, AGC, and a custom window feature that fits the boreoscope image to the camera chip. Outputs include composite video, S-Video, and a USB 2.0 digital port for capturing images to a PC. A variety of boreoscope probes ranging in diameter from 0.35mm to 2.7mm can be attached via a bayonet quick mount.
