650nm 5mW Micro Red Dot Laser Module

650nm 5mW Micro Red Dot Laser Module (Ø4×13.7mm)

The 650nm 5mW Micro Red Dot Laser Moduleis a compact semiconductor laser designed for laser pointers, precision positioning, alignment, measurement and OEM equipment integration.

With an ultra-smallØ4×13.7mm brass housing, this module is suitable for space-limited devices that require a visible red laser source with stable output and compact mechanical dimensions.

The 650nm wavelength provides a clear red laser dot, while the brass housing offers good thermal conductivity and mechanical stability for continuous operation.

Technical Specifications

Ultra-Compact Ø4×13.7mm Design

The key advantage of this module is its miniature size.

At only4mm in diameter and 13.7mm in length, it can be integrated into compact devices where conventional laser modules are too large.

Typical integration applications include:

• Laser pointers
• Handheld devices
• Miniature instruments
• Compact sensors
• Embedded optical systems
• Portable electronic equipment

Optical Performance

The module produces a visible650nm red laser dotsuitable for targeting, positioning and indication.

Typical optical characteristics:

• Wavelength:650nm
• Output power:5mW
• Laser color:Red
• Beam pattern:Dot
• High visual contrast for short- and medium-distance indication

Actual spot size, visibility and working distance depend on focusing configuration, ambient lighting and target surface.

Brass Housing

The all-metal brass housing provides several advantages:

• Good thermal conductivity
• Stable laser diode mounting
• Compact mechanical structure
• Improved durability
• Easy integration into OEM devices

The Ø4mm housing is especially useful for applications with strict space constraints.

Photex Laser provides micro 650nm red laser modules for laser pointers, positioning, alignment, measurement and compact OEM optical applications.
