Detroit, Mich. A new a high speed, high accuracy laser nano sensor (LNS) from LMI Technologies (USA), Inc. offers an improved resolution as fine as 0.7 nanometers at speeds up to 200 kHz. It features a miniature sensor head and a small spot size for use in tight work spaces. High-tech industrial applications include micro-positioning polished components such as silicon wafers, lenses or circuitry as well as the measurement of vibration, thickness, roughness and precision switching.
The company said the patented, highly precise LNS has one of the fastest response rates in the industry and a spot size ranging from 1 to 6 microns. This allows for displacement measurement within a few nanometers on quantifying surface roughness of any highly reflective surfaces such as glass, aluminum, stainless steel or mirror-type surface that can be positioned perpendicular to the laser beam path.
Available in four standard models, the LNS offers a measurement range of 0.00016 in. to 0.005 in. (4.0 to 130 micrometers) and an operating distance of 0.09 in. to 1.0 in. (2.3 mm to 26 mm). Depending on the target, accuracy ranges from 0.022 nanometers to 0.75 nanometers. The standard operating temperature range is 32°F to 120°F (0°C to 50°C).
Measuring 2.3 in. (60 mm) length x 0.98 in. (20 mm) diameter, the sensor includes two high-grade lenses and a specialized miniature laser diode grating unit (LDGU) which functions as the sending/receiving unit. It also includes a holographic beam splitter, an electronics housing powered by ±15 Vdc, and an analog output for distance and intensity. Analog output is ± 5 Vdc of the measurement range. Custom designs are available.
The nanosensor is priced at $4,300. Delivery is four to six weeks.
