Ball Lenses

Antireflection (AR) coated ball lenses from Deposition Sciences, Inc. (Santa Rosa, CA) are available in a variety of glass indexes and sizes from 200 microns up to 10.0 mm diameter. They feature transmission values of greater than 99.5 percent in indexes of up to nd 2.0 @ 550 nm. The AR-coated ball lenses are stable over temperature and humidity changes, and are resistant to most chemicals. Meeting or surpassing the rigid Mil-C675 testing standards for severe abrasion, adhesion, humidity and salt fog tests, the ball lenses can be used in fiber to fiber, diode to fiber, and/or fiber to detector coupling tasks.

Twyman-Green Interferometer

The PhaseCam™ 5030 from 4D Technology (Tucson, AZ) is a high-performance, Twyman-Green interferometer developed specifically to measure meter-class optics for terrestrial and space-based telescopes. Unlike traditional phase-shifting interferometers, the PhaseCam utilizes Dynamic Interferometry® to acquire all measurement information in a single exposure, enabling measurement in the presence of vibration and air turbulence. Using a high-speed optical phase sensor that eliminates the need for slow, piezo-based phase-shifters, the PhaseCam 5030 can measure more than 10,000 times faster than a conventional phase-shifting interferometer. The turnkey PhaseCam system includes the interferometer, high-speed computer system, and extended-length cables for remote operation. 4Sight™ analysis software provides extensive 2D and 3D analysis options, as well as comprehensive data filtering, masking, database and import/export functions.

Wide Angle Zoom Adapter

The 287-000 Series Wide Angle Zoom Adapter from Resolve Optics Ltd. (Chesham, UK) provides a true 0.5x field of view and maintains minimal distortion and high resolution throughout the zoom range of a camera. Each production lens is individually collimated to maintain the full focus range of the prime lens. Incorporating an M37 mounting thread, the adapter enables most zoom lens/camera combinations with a standard 45° field of view to achieve a 90° field of view.

Optical Channel Monitor

AMS Technologies (Martinsried, Germany) has introduced the Optical Channel Monitor, which provides critical data on optical transmission signals present in DWDM networks with a scan time of less than 100msec. The Optical Channel Monitor includes a fixed fiber grating and a high resolution detector array, resulting in an accuracy better than 50 pm. The recorded data can be used to determine system functionality, identify performance drift or as feedback data for controlling telecommunication network elements. The OCM is designed to cover a wide range of spectral bandwidths and channel spacing applications (100, 50 and 25 GHz).

Reflective Semiconductor Optical Amplifier

The new reflective semiconductor optical amplifier (RSOA) component from CIP (Ipswich, UK) provides high-speed transmission capability for wavelength division multiplexing passive optical networks (WDM-PON) by reflecting and modulating a “seed” light that is transmitted throughout the network. The component is capable of delivering more than 20 dB of optical gain and provides optical data transmission at gigabit Ethernet rates without the need for a local wavelength stabilized source or temperature control. The RSOA component is available in a TO-56 can package for easy integration into micro-optic assemblies. Data can be modulated at rates of up to 1.25 Gbits/sec from standard production devices. Polarization sensitive or polarization insensitive versions are offered.
