    Ultra-High-Temperature Quartz Glass Rods and Discs

    Able to withstand temperatures up to 2100° F, this quartz glass is useful in high-temperature applications that also require optical clarity, such as high-intensity lighting, fiber-optic production, and optical lens systems. It provides excellent UV transmission, as well as high transmission in the visible and infrared ranges.

    These sheets won't deform when exposed to temperatures up to 2100° F or from drastic temperature changes. Compared to borosilicate glass, they handle five times more heat. These sheets are highly pure and will not leach impurities into laboratory or electronics manufacturing processes. They're also optically clear and have excellent UV transmission, making them ideal for UV purification systems.

    Inspect micrometer spindle and anvil tips to identify whether they're worn or out of parallel. These discs help you keep your micrometer measuring accurately, especially after repeatedly measuring hard items such as ball bearings. Place them between the anvil and spindle and look at the resulting light pattern on the glass.
    Optical flats determine if your anvil is no longer flat. If the lines you see are curved, your anvil is worn.

    Inspect micrometer spindle and anvil tips to identify whether they're worn or out of parallel. These discs help you keep your micrometer measuring accurately, especially after repeatedly measuring hard items such as ball bearings. Place them between the anvil and spindle and look at the resulting light pattern on the glass.
    Optical parallels determine if your anvil and spindle are parallel. You’ll know your micrometer is out of parallel if the spindle side reflects a different number of lines than the anvil side. Each parallel includes four discs to check each quarter-turn of your spindle and identify where it has worn down.
