We fabricate and supply quartz microscope slides of optical-grade, high-purity synthetic fused silica. Unlike conventional quartz slides made of lower-quality natural fused quartz, our UV-transparent silicon dioxide object carriers are manufactured of amorphous, optical-grade fused silica, customarily used for sophisticated optics. Therefore, our quartz slides feature a significantly higher transmission for lower UV wavelengths than fused quartz microscope slides can provide and offer much better inner quality.

The surfaces of our quartz glass slides are optically polished on both sides. They offer more than 80 % light transmission even at a very low UV wavelength of 185 nm, whereas conventional fused quartz slides typically only transmit less than 50 %. Excellent purity reduces absorption losses in the deep ultraviolet wavelength range to a minimum, allowing special scientific applications in DUV microscopy.

Furthermore, our quartz microscope slides feature the exceptional flatness and surface quality, known from optics. Moreover, they offer the extraordinarily high chemical resistance of amorphous quartz, thus enabling contamination-free sample storage solutions for the laboratory. No substances or chemicals dissolve into the sample from the inert microscope slide or coverslip, representing an essential requirement for many demanding microscopy applications in medical cell research, life science, analytics, biotechnology, and specimen storage equipment in the lab.

Präzisions Glas & Optik GmbH supplies all standard dimensions of microscope slides used in science (see table). As a manufacturing company, we can produce nearly any shape and size and are not limited to standard dimensions. Hence, we can always provide a solution whenever you need round quartz plates, cover glasses, square cover slips, or other quartz components.

Our delivery time for microscope slides of quartz glass with custom dimensions is just as short as for the listed sizes. Our 48-hour express service is possible for any thickness in the thickness table if you require ultra-fast delivery of custom-sized quartz microscope slides. This unique option offers the manufacturing and shipping of custom-sized quartz microscope slides within two working days after receiving your order, provided no other complex manufacturing steps are required. When you order via our 48-hour Express Services, you quickly have your tailored quartz slide on your lab table to continue your project or daily business without delay.

Custom thicknesses are available on demand.
The bold numbers represent the science lab's most common microscope slide standards. However, if smaller slide dimensions also work in your equipment, please consider that these sizes might significantly lower the piece price over the standardized quartz slide sizes. For example, the price of a slide at 23mm × 66mm × 1mm is considerably lower than that of a 25mm × 75mm × 1mm size. Other products like round plates, custom shapes, and coverslips are possible.
