EXTRATECH

These are the parts used in machine support.Made by aluminium, machining and doing the sandblasting and natural anodize surface treatment.

These parts were made by stainless steel,which is produce from custom-made by drawing picture,we are strictly control the tolerance range to provoide perfects products.

Knight Optical can offer you Plane Mirrors (general, λ/1 and λ/4), for use within Laser Distance Measurement Applications in a range of materials such as Soda-lime float glass, white float glass, and BK7 glass. Plane mirrors also known as front surface mirrors or first surface mirrors are used widely within Laser Distance Measurement applications. As stock we hold a number of general purpose, λ/1 and λ/4 with a range of up to 6 types of coatings such as Enhanced Aluminium, Ali/SiO2 and Ali/Mgf2. Our general purpose grade mirrors are made from good quality float glass and generally available in thicknesses of 1mm, 3mm and 6mm as standard. Laser Distance Measurement devices utilise the use of a laser beam to be able to determine the distance of an object. How optical mirrors are used in conjunction with these devices is that, a mirrored surface can be measured with a laser tracker; which will help determine the distance between the laser distance Read PDF for full information..

The BH25 is a high resolution exposed linear encoder with interferometric measurement signal generation. The BH25 scale has a graduation period of 1µm. The interferometric laser scale principle generates a sinusoidal measurement signal with a signal period of 250nm in the read head. The BH25 is characterized by its small size and high signal quality. It is suitable for resolutions of up to 3.8pm. Due to the reflective scanning and the small design it is perfectly suited for high accuracy X/Y stages with linear motor drive as well as for measurement applications
