The Focovision by Reflection SR-2 is used in the production of semifinished lenses, glass and metal molds,but also in prescription laboratories to control the incoming semi-finished lenses. It measures the surface optical power by reflection on one point with a high degree of accuracy. The measured value can be expressed in curvature or in diopter. The Focovision by Reflection has become a worldwide reference instrument throughout the ophthalmic industry. High accuracy (0.01D for the base power, less than 0.01D for the residual astigmatism of the instrument) Very high reproducibility Precise and reproducible positioning of the lens according to reference points marked over the lens surface Simple and rapid autocalibration procedure No moving parts (behaviour stability, simple lighting system, ...) Linear instrument response (no mechanical adjustments are necessary) Reliability : Image quality control & automatic correction of dust effect

The TPS70950DRVR is a 150mA linear voltage regulator from Texas Instruments. It is designed to provide a regulated output voltage from an input voltage of up to 6.5V. It has a wide operating temperature range of -40°C to 125°C and is available in a 6-SON (2x2) package.

The LTC6090CS8E#TRPBF is a general purpose instrumentation amplifier from Linear Technology. It is a single-channel, rail-to-rail amplifier with a wide common-mode input voltage range. It features low offset voltage, low noise, and high common-mode rejection ratio (CMRR). The amplifier is housed in an 8-pin SOIC-EP package and is ideal for applications such as signal conditioning, data acquisition, and medical instrumentation

The LMP8645HVMKE/NOPB from Texas Instruments is an instrumentation amplifier specifically designed for high accuracy data acquisition. It features a wide common mode voltage range of -2V to +76V and CMRR-Common-Mode-Rejection-Ratio of 95 dB, which minimizes noise in applications requiring high common mode rejection such as medical, industrial, and instrumentation systems. It has high gain accuracy over a wide temperature range and excellent gain non-linearity and temperature coefficient. This instrumentation amplifier operates from a 2.7 V to 12 V supply voltage and has a Maximum-Operating-Temperature of +125°C and a Minimum-Operating-Temperature of -40°C. This product is available in the TSOT Package-Case.

The TPS78318DDCT is a low-dropout (LDO) linear voltage regulator from Texas Instruments. It is designed to provide a regulated output voltage of 1.8V with a maximum output current of 150mA. The device features a low quiescent current of only 1.2mA and a low dropout voltage of only 0.2V. It also features a wide input voltage range of 2.7V to 5.5V and a fast transient response
