Review THORLABS Dual-axis Goniometer Stage Micrometers Stack Base

The Thorlabs GNL20 Dual-Axis Goniometer Micrometers, along with the GNL18 and GNL10 stack base, form a comprehensive and precise alignment toolkit for various optical and mechanical applications.

The GNL20 Dual-Axis Goniometer Micrometers are designed to provide precise and repeatable angular adjustments in two axes, offering users the ability to fine-tune the orientation of components with an accuracy of 0.01 degrees. Each micrometer features a sturdy, anodized aluminum housing, ensuring durability and resistance to environmental factors. The micrometers also come with a 0.1-degree graduation scale, making it easy to read and adjust the angle.

The GNL18 and GNL10 stack bases are designed to securely hold the GNL20 micrometers, providing a stable and robust platform for angular adjustments. The GNL18 base features six 1"-40 UNC threads, allowing for easy attachment of various accessories, while the GNL10 base provides a compact and lightweight alternative with four 1/4-20 UNC threads. Both bases are made of anodized aluminum, ensuring durability and strength.

The GNL20 Dual-Axis Goniometer Micrometers, in combination with the GNL18 and GNL10 stack bases, offer a versatile and precise alignment solution. This toolkit is ideal for applications in the optical, mechanical, and semiconductor industries, where precise angular adjustments are required for alignment and assembly of components. With its robust design, high accuracy, and easy-to-use components, the Thorlabs GNL20 Dual-Axis Goniometer Micrometers and GNL18/GNL10 stack bases are an essential addition to any precision alignment toolkit.

1. Precision: The GNL20 features a high resolution of 0.0002 degrees, ensuring precise angular measurements.

2. Stability: The stack base design provides a stable platform for the goniometer, reducing the risk of vibrations affecting the measurements.

3. Compatibility: The GNL20 is compatible with various Thorlabs accessories, such as the GN18 and GN10 rotary stages, allowing for versatile setups.

4. Durability: Thorlabs products are known for their robustness and durability, ensuring long-term use.

1. Price: The GNL20 is a high-end product, and its price may be prohibitive for some users.

2. Learning curve: Users may need to familiarize themselves with the operation of the goniometer and its associated software to fully utilize its capabilities.

3. Size and weight: The GNL20 is a relatively large and heavy device, which might be a disadvantage for users with limited lab space or mobility requirements.

The Thorlabs GNL20 Dual-Axis Goniometer Micrometers GNL18 GNL10 Stack Base is an excellent choice for users requiring high-precision angular measurements in their experiments. Its compatibility with various Thorlabs accessories, durability, and high resolution make it a valuable addition to any lab. However, its high price and size may be a deterrent for some users. If precision and versatility are essential factors in your experiments, the GNL20 is an excellent investment.

If the GNL20's price and size are not limiting factors, we highly recommend this product for users in fields such as optics, photonics, and materials science. Its precision and compatibility with other Thorlabs products make it an indispensable tool for these applications. For users on a tighter budget, alternative options with lower resolution or fewer features might be more suitable. Always consider your specific requirements and budget before making a purchase.

Details:

Breadboard not included. In the photo above you can see to left front 3 posts that randy, my machinist made load into Olympus bhaji focus block be seen rear of. I am selling this as one unit. To the right of 3 posts you can see Thorlabs post base that randy modified and counter bored so we could use 3/8-16 thread screws.

This is from my late friend whom this belonged. Hopefully someone can use what Richard put so much love and attention money into. Behind the Thorlabs post base and in front of Olympus bhaji focus block you can see plate that randy made so I could load angle bracket to right block to slide. Below is a he wrote himself.

To the right of plate mentioned is Newport 481-a rotating stage. These 3 posts can be used separately or in combination they all screw together lengths of 4, 6, 8, 10, 12, 14, and 18 so that I adjust the height assembled subject carrier.
