Iodine-Stabilized He-Ne Laser "Model 100" reimported after laser repair Winters' Iodine-Stabilized He-Ne Laser "Model 100" is used at the Technical Research Institute, Japan Society for the Promotion of Machine Industry as the length Standard unit together with Firm NEOARK Corporarion's Iodine-Stabilized He-Ne Laser for the calibration of laser units from Japanese companies. In Japan we had known that the Micro-g LaCoste Absolute Gravimeter combined Winters Model 100 Laser unit and several government offices used this absolute gravimeter. However a famous big corporation uses several sets of Winters Model 100 itself for the calbration of his products. There was very little leak in the laser tube this time and his unit was unstable. We obtained the Reimport Permission of that Laser unit and sent it back to Firm Winters to repair in Longmont near Denver, Colorado, and in this area there are Laser Laboratory of NIST. After repair works we reimported and reinstalled it at the laboratory of the big corporation, the Model 100 runs very good now.Iodine-Stabilized He-Ne Laser "Model 100 & 200"

Laser Interferometer using Fiber Optic Cable "ZLM 900-LSI"  Firm JENAer Meßtechnik GmbH manufactures Laser Interferometer using Fiber Optic Cable "ZLM 900-LSI". This system is Dual-Frequency Laser Heterodyne Operation as the same as "ZLM 500/700". However this system doen't need a tripod for the Laser Measuring Head. The Laser Light is fed through the Fiber Optic Cable, therfore the setting and handling are vry simple. The high-frequency signal procesing enables measurements at very high object speeds up to 4m/s. This system is for a laptop PC.The leaflet is only 1 page in Japanese. please click here ! We have a technical material in Japanese "The principle of Laser Interferometer and its Application to Length Measurements".  Please ask per E-mail about the technical material in Japanese.Dual-Frequency Laser Interferometer "ZLM 500/700"

Standards for Optical Surface Measuring Instruments 2080 
There is a tendency for a roughness measurements by optical surface measuring instruments as interference microscopes with automatic image processor. This is because the optical and non-contact measurements are very quick. Then almost instruments are calculating the roughness parameters based on ISO and/or JIS, however it is not clear that the evaluation is the same as the Standards. Becasue the existing Standards for the roughness are intended for the stylus instruments not for the optical surface mesuring instruments. The comparison between the stylus and opticla instruments gives many results but they don't satisfy. For example, a horizontal resolution measured by interference microscopes is too short and this instrument cannot get the tracing length as long as the Standards. This announced standard 2080 is the one for the depth which is groove-grinded on the flat surface. The features are:1) The program routine of optical instruments is on the assumption that the measuring surface is flat, and 2080 is made to flat. 2) The groove has oblique wall which gives the clear results for interference measurements. 3) The reflectivity of the measuring surface is high which gives better S/N for optical instruments. 4) There are 6 grooves.  0.24, 0.75, 2.4, 7.5, 24, 75µmAbout the detail of the standard 2080 is refered to the following PDF-file in Japanese.  Calibration Standard 2080 (only in Japanese)
Measurements Standards for the Calibration of the Stylus Prtofile Instruments
Depth Measurement Standard 2060 and Roughness Measurement Standard 4058 
Under the ISO 9000 series which are Standards for Quality assurance and Quality control the traceability during the manufacturing process is requested and the roughness measurements are the same. The Depth Measurement Standard 2060 (above sketch) and Roughness Measurement Standard 4058 (right sketch) are the same as JIS B 0659-1 or ISO 5436-1 or the Standard of PTB, German National Laboratory.This depth measurement standard 2060 is calibrated according to SI unit and the stylus movement of Stylus instruments are traceable to SI Units. This Standard 2060 is Type A2 of the Standard and 40 x 20 x 10 mm made by glass and the calibrated depths are located in the center area. The Standard has 2 kinds, 6 grooves and 3 grooves as the left and center drawings. The 6 grooves is Type No.2060/01/6/Pk and they are 0.25/0.6/1/3/6/9 µm. The right interference fringe shows 3µm depth. The 3 grooves is Type No.2060/01/3/Pk and they are 1/4/9 µm. This time Type No.2060/01/1/Pk for 1 groove is newly on sale. The right drawing is the Roughness Measurement Standard 4058, Type D1 of the Standard, for calibrating the roughness parameters with the size of 40 x 20 x 11.3 mm made by hardned Stainless steel. The measured surface has an area of 17 x 5 mm and an irregular profiles repeated in 2-4mm length. The irregular grinding profiles can check the waviness and the effect of the stylus radius comparing standards whose profiles are sine waves profiles or pyramidal wave profiles. The certificate shows the using Gauss filter and 3 roughness parameters as Ra, Rz and Rmax. Ra with about 0.2µm is Type No.4058/01A1/Pk, Ra with about 0.5µm is Type No.4058/01A2/Pk and Ra with about 1.5µm is Type No.4058/01A3/Pk. Superfine Roughness Measurement Standards 2070

Firm Winters Electro-Optics, Inc. USA is manufacturing the Model 100 Iodine-Stabilized He-Ne Laser for laboratory and field applications in precision measurement, laser spectroscopy and standards works.
Firm Winters Electro-Optics, Inc. USA sells new Model 200 Offset-Locked Iodine-Stabilized He-Ne Laser, which offers the same frequency stability and accuracy of the Model 100 with an 8x increase in output power. The Model 200 Laser was designed to remedy the complications that arise when using an intra-cavity iodine-stabilized laser for high accuracy interferometric measurements.
Firm JENAer Meßtechnik GmbH, Germany has become independent from the Optical Division of Carl Zeiss Jena Laboratories, and manufactures the Dual-Frequency Laser Interferometer and Precision Thermometer. 
The picture shows the Dual-Frequency Laser Interferometer System 'ZLM' of Firm JENAer Meßtechnik GmbH. The 640 MHz beet frequency of its two modes is quadrupled for the purpose of signal processing.

Advantages
Firm Halle-Präzisions-Kalibriernormale GmbH, Germany manufactures measurement standards for contact stylus roughness testers and can deliver it with PTB Certificate. The traceability is required in production line for ISO 9000 series. The Halle's standards are used for calibration of roughness testers in production lines too. In Japan recently many Japanese Industrial Standards (JIS) for roughness measurement are revised according to the standardization of ISO. The Halle's standards are conformed to JIS B0659-1:2002 (ISO 5436-1:2000) "GPS-Surface Texture: Profile Method; Measurement standards-Part 1". Firm Halle manufactures Type A2, Type D1 and Type D2 in conformity to JIS (ISO).

The importance of quality control is increasingly required because of the recent demand for nano-technology. The quality management of fine surface is difficult but a must. If the stylus radius is changed about 1µm, then the result has big difference in the Nano-world. Firm Halle manufactures the standards whose values are Ra for 20 to 100nm and Rz for 100 to 500nm and delivers with PTB Certificate.
Firm Retter Automation+Messtechnik GmbH, Germany manufactures Ball plates for calibrating CMMs, and there is the Certificate of PTB for these ball plates. There are 2 kinds of ball plate with ceramic balls or steel balls, and 3 kinds in dimension; 300x300mm, 400x400mm and 500x500mm. We have delivered one ceramic type to former National Research Laboratory of Metrology.
