Machine Calibration Plate - 7 Inch

SHARE

CALIBRATION PLATE: This is a precision machine calibration plate containing a series of dots placed very accurately in precise locations, whose position can be captured by camera or video and relayed back to the system drive to ensure that the machine guides/drives/rails are correctly calibrated for position. The dots are placed on a multiple of a 25mm grid, making it easy to calculate any discrepancies found after calibrating. Each grid will be supplied with then excel spreadsheet giving the positions. The dots are imaged in low reflective chrome pattern  - which is hard and durable and allows for regular cleaning of the plate. the colour of the chrome depends on which base material you require. Each plate type has a pattern of 4 different size, allowing for different resolution camera`s to capture them at different zoom levels.  


Target 1:  Dot size, 10mm

Target 2:  Dot size, 1mm

Target 3:  Dot size, 0.2 mm

Target 4: Crosshair, 10mm with 0.2mm stroke width

 

BASE MATERIAL  
177mm Soda Lime glass (3mm thick) with a low reflective brown chrome pattern.
200mm White Opal glass with a low reflective black chrome pattern.
See SPECIFICATIONS for details on dimensional stability. Please contact us for availability on Fused Silica (Quartz) materials which have a better thermal expansion coefficient.

 

COATINGS  
We can apply either a solid white, black or translucent plastikote painted coating to the plate. You can choose this to be applied to the front or rear face of the plate. Additionally, anti-glare coatings can be applied to reduce the reflectivity of the top surface when reflected illumination is used. 

 

PRODUCTION TURNROUND  
Our standard turnround is 7-10 days for this product. We can offer faster services if required for more urgent orders.



INSPECTION

Full Certificate :   The grid is supplied with a measured calibration certificate that is traceable back to NIST standards. Each plate is individually marked with a serial number. Each plate will be supplied with a spreadsheet giving positions, tolerances
