Small highly accurate holes are a common requirement across a range of industries and applications. Laser-drilled precision pinholes from Oxford Lasers have uses in a variety of applications, including calibrated leak detection, gas/liquid filtering, beam aperturing and spatial filtering.
A standard range of pinholes is available in thin foil, as shown in the table below.
| Pinhole dia (µm) | Disc dia (mm) | Thickness (µm) |
|---|---|---|
| 5, 10, 25, 50, 100 | 3 | 40 |
| 5, 10, 25, 50, 100 | 5 | 50 |
Material: Stainless Steel, pinholes centred to ± 0.01 mm
Pinholes also be produced in thicker matetials, these are suitable for high power laser applications such as spatial filtering. Available dimensions are given below:
Diameter: 50, 100, 150 mm,
Material thickness: 0.5, 1.0, 1.5 mm,
Disc diameter: 25 mm,
Material: Stainless steel, copper, brass, and others
Pinholes and slits can be produced to order for custom requirements, typical dimension ranges available are given below:
Diameter/width: 50 – 200 mm,
Material thickness: 0.1 – 1.5 mm,
Disc diameter: 3 – 25 mm,
Material: Stainless steel, copper, brass, and others
Characteristics of our pinholes include minimal heat affected zone, smooth clean walls with minimal recast and a well defined, sharp edge on the exit side of the hole.
