Composite Inductors
Composite inductors are constructed by inserting a pre-wound coil over pre-press magnetic core and then pressing or molding a magnetic material around this assembly. The composite inductors are very similar to molded but typically offer lower DCR and lower overall losses. Our composite core inductors provide a fully shielded, high energy density, soft saturation solution for applications up to 120Apk. The construction enables the highest energy density of any available SMT inductors and also minimizes acoustic noise. We offer both commercial grade (-40C to 125C) and automotive grade (-55C to 155) in a wide range of platforms from 4x4x2mm to 17x16x13mm.

Laboratory EM current meter / water level and wave height meter
ACM2-RS and ACM3-RS are 2-D and 3-D electro-magnetic current meters for laboratory experiments. The models provide digital output, a high-speed sampling rate and insusceptibility to electro-magnetic noise. ACH-600RS is a highly sensitive capacitance water level meters. With the new system, a maximum of four different sensors can be connected to the compact interface unit, enabling simultaneous recording on a personal computer. Additionally, the system can provide analog output as well as necessary. While conventional water level and wave height meters cannot be used near velocity sensors, our instrument can be as near as 5 cm without increasing noise, due to its special isolated circuit. The result is an innovative system that is capable of achieving highly accurate data.

Isolation Transformers
Osborne’s Isolation Transformers are used to step-up, step-down and isolate voltages in single phase circuits. Isolation may be used to provide output circuit immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the input system. The isolation can allow separate grounds on both the input and output sides of the transformer. Osborne also designs with a range of electrostatic shielding to provide several levels of noise immunity.

A Global Standard for Acoustic Absorption Measurements
Alpha Cabin
The Alpha Cabin has been especially designed for the measurement of acoustic absorption properties of materials and components used for the noise insulation of vehicles. The Alpha Cabin is significantly smaller than normal reverberation rooms and therefore ideally suited to use within limited space capacities. The acoustic absorption of the Alpha Cabin itself is also very low: Thanks to the high level of sound insulation, background noise in the frequency range of interest is kept to a minimum.

Monochromator Gratings - Type IV
HORIBA Scientific produces a wide range of holographic master gratings from which high precision replicas are manufactured.Using Type IV aberration-corrected monochromator gratings, a single concave grating disperses, collimates, and refocuses the light from the entrance slit onto the exit slit. Wavelength scanning is obtained through a simple rotation of the grating.The groove spacing of these gratings is computer-optimized to produce high quality images with a minimum of astigmatism and coma, even at large numerical apertures. Compared with Czerny-Turner monochromators (equipped with one plane grating, one collimating mirror and one focusing mirror), Type IV aberration-corrected monochromator gratings provide much better light collection efficiency and signal-to-noise ratio.
