Recommendations for Powerful 24-VDC Light Source or Laser to Illuminate Cylinder Holes

Question:

Good morning! I'm working on a project that involves shining a light into one end of a cylinder that features two drilled holes along its body. To verify that the holes are indeed open, I'm using a camera to detect the light emanating from both holes. One hole is significantly brighter than the other due to its proximity to the light source, while the further hole allows much less light to escape. I'm seeking recommendations for a 24-VDC light source or a strong laser that could effectively illuminate both holes. Unfortunately, standard flashlights haven't provided satisfactory results. The cylinder measures 2.5 inches in length and 1.5 inches in width, with a hole diameter of 5/8 inch at the opening where I direct the light. Any suggestions or insights would be greatly appreciated. Thank you!

I utilize several of these lighting solutions for machine vision applications. Their prox spot lights could be effective for enhancing visibility in your projects.

Thank you! I will review some of these options and provide updates on my experience if I decide to make a purchase.

I have utilized these ATV lights for both flood lighting and task illumination.

Consider placing a reflective surface at the exit end of the cylinder. This will redirect the light back into the cylinder, effectively illuminating the second set of holes you are currently struggling with.

Frequently Asked Questions (FAQ)

FAQ: Q1: What is the purpose of using a light source or laser in this project?

Answer: A1: The goal is to shine light into one end of a cylinder with two drilled holes to verify that both holes are open. A camera detects the light emanating from the holes to confirm their status.

FAQ: Q2: Why are standard flashlights not effective for this application?

Answer: A2: Standard flashlights do not provide enough illumination to ensure that light effectively reaches and emanates from both holes, especially the one further from the light source.

FAQ: Q3: What are the specifications of the cylinder involved in the project?

Answer: A3: The cylinder is 2.5 inches in length and 1.5 inches in width, with a hole diameter of 5/8 inch at the opening where the light is directed.

FAQ: Q4: What type of light source is being sought for this project?

Answer: A4: Recommendations are being sought for a 24-VDC light source or a strong laser that can effectively illuminate both holes in the cylinder.

FAQ: Q5: Why is there a difference in brightness between the two holes?

Answer: A5: One hole is significantly brighter than the other due to its closer proximity to the light source. The further hole allows much less light to escape, making it more challenging to detect with the camera.
