Figure 1. An R1DS3N Negative Reticle and a DG10-1500 Diffuser shown mounted with the ground side against the reticle. Together, they create an alignment target for a CPS520 Laser Diode Module that is mounted in KAD11F Kinematic Adapter and an LM1XY Translation Mount. The light is incident on the polished side of the diffuser.

Features

  • Positive and Negative Crosshair and Concentric Circle Patterns
  • Available Sizes: Ø19.0 mm, Ø21.0 mm, or Ø1"
  • UV Fused Silica Substrate
  • Patterns Made of Chrome Layer that is 0.120 µm Thick

Reticles are optics designed for insertion in the eyepiece of an imaging system that superimpose either a crosshair or concentric circle pattern on the imaged object. The pattern provides a reference location and allows the imaged object to be centered. Because they are intended to be used in transmission, Thorlabs' line of reticles is made from a UV fused silica substrate, unlike our test targets, which are made from soda lime glass. UV fused silica provides excellent transparency from the infrared down into the ultraviolet.

Many of our reticles are available with positive and negative patterns. The positive reticles consist of high-reflectivity, vacuum-sputtered chrome patterns plated on clear substrates and are useful for front-lit and general applications. The negative reticles use the same chrome coating to cover the substrates, leaving the patterns clear, and work well in back-lit and highly illuminated applications.

All the parts shown here are manufactured at Thorlabs' in-house semiconductor device production facility in Jessup, Maryland. Our extensive production capabilities enable us to provide solutions for imaging system calibration and measurements. We use contact photolithography with a mask aligner to define the pattern on the glass substrate. Once the pattern is defined, we chemically etch the substrates and clean them in a class 100 cleanroom.

Thorlabs also offers a selection of test targets, calibration targets, and stage micrometers for imaging systems.

Transmission for 1.0 mm UVFS Substrate
For a graph that extends to 3.2 µm, please see the Graphs tab.

The following transmission plot was measured at normal incidence using a UV fused silica substrate that was 1.0 mm thick. The transmission for the reticles sold here will be slightly lower because of their 1.5 mm thickness.

what is the thickness tolerance of the 1,5mm thick substrate?
YLohia  (posted 2019-10-02 09:52:38.0)
Hello, thank you for contacting Thorlabs. The tolerance on the thickness of the R19DS11P is 1.4986 mm +0.000/-0.2032 mm. The diameter tolerance is +0.0/-0.1 mm.

* Is it possible to get a customized Positive Concentric Circle Reticle
YLohia  (posted 2019-01-31 09:32:42.0)
Hello, thank you for contacting Thorlabs. Custom reticles can be requested by emailing techsupport@thorlabs.com with your exact requirements and order quantity. We will reach out to you directly to discuss this further.

Negative Crosshair Reticle, 19mm, UVFS and both positive and negative reticles at 0.5" diameter would be very useful/helpful. Thanks!

Hello. I am using the R19DS13P for alignment. Looking at the reticle under a simple microscope and assuming the cicles to be 1mm apart (500µm line separation) the line width seems to be less than 25 µm (10-15µm). Is this correct? From the description:"The pattern is formed from lines that are 25 µm wide."

Response from Mike at Thorlabs: Thank you for your feedback. The linewidth of the concentric circles should be 10 um, while the linewidth of the crosshairs should be 25 um. We are currently working to get this updated on the website.

Dear Sirs For a high precision alignment telescope built almost solely of Thorlabs components :-) I use your reticles R1DS3N and R1DS3P. Now there is my question: Can you please tell me how precise the shape of the circles is deviating from the ideal circular shape? This question I should answer to my project steering comitee here. Thanks in advance and best Regards Michael Wegner Senior Engineer Metrology Department Swissoptic AG Heerbrugg, Switzerland P.S. Please answer by E-Mail: michael.wegner@swissoptic.com

Response from Jeremy at Thorlabs: The centration tolerance is ±125µm. The outer diameter tolerance is +0.0/-0.2mm. I will contact you via e-mail to discuss about this.

The custom reticles tab shows some useful reticles. Why don't you sell those too?

Response from Tim at Thorlabs: Thank you for contacting us! The custom reticles tab was made to describe our capabilities for customs. There is a large tooling cost for releasing a new reticle and so we chose the most popular versions for initial release. We also have more test targets at http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=4338. We appreciate feedback on designs that would be most useful for you as we continue to release new products. I see that you didn’t leave any contact information but we would be interested in your feedback. To discuss this further please contact us at techsupport@thorlabs.com.

Crosshair Reticles

R19DS11P in SM1AD19 Mounting Adapter
  • Crosshair Extends to the Edge of the Optic
  • Positive Crosshair Available in 19.0 mm, 21.0 mm, and 1" (25.4 mm) Diameters
  • Ø1" (Ø25.4 mm) Negative Crosshair Option

Our crosshair (crossline) reticles are used to superimpose a reference pattern on an object being imaged. The crosshairs, formed from lines that are 10 µm wide, span the entire diameter of the optic. Made by plating chrome onto one side of a 1.5 mm thick UV fused silica substrate, these optics provide greater than 90% transmission in the 200 - 1200 nm spectral range.

The Ø19.0 mm reticle can be adapted to Ø1" mounts by inserting it into the AD19T or SM1AD19 Mounting Adapters. The AD19T has a smooth outer perimeter, making it compatible with any standard Ø1" mount, while the SM1AD19 has an external SM1 (1.035"-40) threading, providing the ideal match for Thorlabs' line of SM1-threaded optomechanics.

R19DS13P in AD19T Mounting Adapter
  • Ten Numbered Concentric Circles Increasing in Diameter by 1 mm, Superimposed on a Crosshair
  • Positive Pattern Available in 19.0 mm, 21.0 mm, and 1" (25.4 mm) Diameters
  • Ø1" (Ø25.4 mm) Negative Pattern Option

Our concentric circle reticles consist of a centered crosshair and ten numbered concentric circles. The innermost circle is 1 mm in diameter, with each subsequent circle increasing in diameter by 1 mm. The pattern is formed from lines that are 10 µm wide. Made by plating chrome onto one side of a 1.5 mm thick UV fused silica substrate, these optics provide greater than 90% transmission in the 200 - 1200 nm spectral range.

The Ø19.0 mm reticle can be adapted to Ø1" mounts by inserting it into the AD19T or SM1AD19 Mounting Adapters.
