18+1 Rectangular Groove Quartz Substrate 120x5x3.5mm Optical
Component Carrier
Product NameThe 18+1 Rectangular Groove Quartz Substrate is a precision
machined fused quartz platform designed for carrying optical
components, spectrum testing samples and micro analytical
specimens. With an overall dimension of 120x5x3.5mm, the substrate
features 18 standard rectangular grooves plus 1 spare groove, each
machined to a uniform width of 1.8mm with neat and consistent
depth. The double-sided high-precision polished surfaces provide
superior flatness and a scratch-proof finish, protecting delicate
workpieces during loading and unloading. Manufactured from high
purity quartz, the substrate offers excellent high temperature
resistance and chemical stability, making it a durable and reliable
platform for precision optical testing and laboratory applications.

- Neat and uniform groove depth: All 18 standard grooves and the spare slot are machined to
consistent depth and geometry, ensuring even seating of workpieces.
- 18+1 groove design: The extra spare groove provides flexible capacity for additional
samples or replacement positioning during testing.
- Double-sided high-precision polishing: Both faces are finished to a smooth, scratch-resistant standard
that protects optical components and samples from damage.
- High purity and high temperature resistance: The fused quartz body withstands elevated temperatures without
deformation, softening or contamination.
- Excellent chemical stability: The substrate resists moisture, weak acids and common cleaning
reagents, keeping the groove surfaces clean and reliable over long
service life.
ApplicationThe 18+1 Rectangular Groove Quartz Substrate is designed for
laboratory and optical environments where precise, stable placement
of small components is required. It is widely used as an optical
component carrier, holding lenses, mirrors and filter elements
securely in machined grooves during inspection and assembly. In
spectrum testing equipment, the substrate positions micro samples
at a consistent height and orientation, improving the repeatability
of spectral measurements. The platform also serves as a micro
sample placement platform for analytical instruments, providing a
clean, flat and chemically inert surface that will not interfere
with measurement results. Thanks to its tight groove tolerances and
superior flatness, the substrate is particularly suited to
precision optical testing applications that demand dimensional
accuracy and scratch-free handling of valuable workpieces.
Advantages- Tight dimensional tolerance for grooves: Groove width and depth are controlled within narrow limits,
guaranteeing consistent seating and reliable positioning of
components.
- Superior flatness: High-precision polishing delivers a level reference surface that
supports stable and repeatable optical measurements.
- Scratch-proof during workpiece handling: The smooth polished finish minimizes the risk of scratching
lenses, mirrors and samples during loading and unloading.
- Ideal for precision optical testing: The combination of high purity material, precise machining and
stable geometry makes the substrate a dependable platform for
demanding inspection workflows.
