How to Calculate Height of Collimation
Collimation is a crucial aspect of optical systems, ensuring that light travels along the system’s axis. Calculating the height of collimation is essential for designing and optimizing these systems. Our calculator simplifies this process, making it accessible to everyone.
- Enter the distance to the target in meters.
- Enter the diameter of the collimating lens in meters.
- Click the ‘Calculate’ button.
The formula for calculating the height of collimation (h) is:
h = (d / 2) * (1 / tan(θ))
where d is the diameter of the lens, and θ is the half-angle subtended by the lens at the target.
| Diameter (m) | Height of Collimation (m) |
|---|---|
| 0.1 | 1.59 |
| 0.2 | 3.98 |
| 0.3 | 6.37 |
- Always use accurate measurements for the best results.
- Consider the impact of atmospheric conditions on collimation.
- Regularly recalculate collimation height to account for system changes.
What is collimation?
Collimation is the process of aligning the components of an optical system so that they are parallel to the system’s optical axis.
