Are custom dimensions, such as specific outer diameters (OD), available?

SyronOptics offers custom dimensions for their optical filters, including specific outer diameters (OD) and rectangular sizes.

Based on their technical resources and product listings, here is how they handle custom sizing:

1. Custom Sizing Options

SyronOptics provides a dedicated Optical Filter Dicing Calculator on their site, which confirms they can process custom dimensions from larger wafers.

  • Round Filters: You can specify a custom diameter (mm).
  • Rectangular Filters: You can specify custom X (width) and Y (height) in millimeters.
  • Wafer Input: They typically work from standard wafer sizes (60mm, 80mm, or 100mm squares) but also allow for custom wafer inputs to calculate the yield for specific filter sizes.

2. Common Standards and Mounts

While they provide custom cuts, they also support industry-standard mounting diameters if you are looking for a standard fit rather than a completely unique dimension:

  • Metric: M22.5, M27, M30.5, up to M82.
  • Imperial/Threaded: SM05 (0.5"), SM1 (1"), SM1.5, and SM2.
  • Clearance: Their guidelines suggest that for a standard mount, the filter diameter is typically cut ~0.2mm smaller than the mount's clear aperture (e.g., a 24.8mm filter for a 25mm mount) to ensure a proper fit.

3. How to Order

Since the website's checkout often lists standard "off-the-shelf" sizes, custom dimensions usually require a direct inquiry:

  • Contact: You can email for specific dimension requests.
  • Lead Time: Custom dicing from existing wafers is generally faster than a fully custom coating run, but you should verify current lead times for precision cutting.
