What Are Laser Sights?
Let’s start with the basics. A laser sight is a device that’s attached to a firearm to help improve aiming precision. Unlike traditional iron sights, which rely on aligning mechanical notches and posts, laser sights project a laser beam onto the target.
History of Laser Sights
Laser sights have come a long way since their inception. They first emerged in the 1970s and have evolved tremendously since then. Early models were bulky and cumbersome, making them less practical for widespread use. However, advancements in technology and materials have resulted in compact and reliable laser sights available today.
Types of Laser Sights
Here are some common types of laser sights you’ll encounter:
| Type | Description |
|---|---|
| Red Laser | Most common type, effective indoors and in low-light conditions. |
| Green Laser | More visible in daylight, but typically consume more battery power. |
| Infrared (IR) | Used with night vision equipment, invisible to the naked eye. |
How Do Laser Sights Work?
The science behind laser sights is pretty fascinating. Essentially, they produce a focused beam of light that’s emitted in a straight line. Here’s a closer look:
The Laser Diode
The core component of any laser sight is the laser diode. This tiny electronic device generates the laser beam. When electricity is supplied to the diode, it excites the atoms within, causing them to emit photons (light particles). These photons are focused through a lens to create a narrow, coherent beam of light.
Power Source
Laser sights require power to operate, most commonly provided by batteries. Depending on the design, the battery type and lifespan can vary. For instance, many compact models use small button cells, while larger tactical sights may use AA or CR123A batteries.
Beam Focusing
The beam produced by the diode isn’t inherently focused. It’s the job of the optical lens to refine it into a precise, straight beam. This focused beam is what ultimately helps you aim your firearm more accurately.
Mounting Mechanisms
How do you attach a laser sight to your firearm, you ask? Laser sights can be mounted in several ways depending on the firearm and the sight design:
- Rail Mounts: Many modern firearms come with Picatinny or Weaver rails, making it easy to attach laser sights.
- Trigger Guard Mounts: Some laser sights are designed to attach around or in front of the trigger guard.
- Grip Replacement: Certain models involve replacing the firearm’s grip with one that has a built-in laser module.
