Keep your view clear, choose sapphire viewports instead of quartz

• When using the Laser Endpoint Detector having a clear picture is essential in order to position the laser on the area you need to monitor.
• By using Sapphire windows on the viewport the view will stay much clearer for much longer
• When your view is clear it is far easier to align the Laser EPD and improves the accuracy of the depth monitoring

Sapphire window benefits:

• Clear vision allows accurate placement of laser spot
• Sapphire stays clear for much longer in the harsh etch environment
• Direct replacement no changes required
