Compare the ZMI 7724 Laser Module and Delivery Module to decide which fits your interferometry setup. Understand beam size options, compatibility, and cost trade-offs.
Quick Answer
If you need the actual laser source for your interferometer, choose the ZMI 7724 Laser Module. If you already have the laser and need to route the beam to your test setup, the ZMI 7724 Delivery Module is the compatible companion.
Understanding the Two Components
The ZMI 7724 Laser Module is the core laser source, while the Delivery Module is designed to work with it for beam delivery. They serve different roles in your optical system.
The laser module is the higher-cost component, reflecting its role as the primary source. The delivery module is a lower-cost accessory that lets you adapt the beam to your setup.
Beam Size Options and Compatibility
The ZMI 7724 Laser Module is configured for a 10mm beam size. The Delivery Module offers two options: 6mm (standard) and 12mm. This means you must ensure the delivery module's beam size matches your system's requirements.
Because the laser module is fixed at 10mm, you cannot change its beam size. If your setup requires a different beam size, the delivery module's options give you flexibility, but you must verify compatibility with your existing optics.
Trade-Offs at a Glance
- Laser Module: Core Source: Provides the laser beam itself. Fixed at 10mm beam size. Higher cost but essential for generating the beam. If you lack a laser source, this is your required purchase.
- Delivery Module: Beam Routing: Companion accessory that delivers the beam to your test setup. Offers 6mm or 12mm beam size options. Lower cost but only useful if you already have the laser module. Check which beam size your system requires before ordering.
- Cost vs. Function: The laser module costs significantly more than the delivery module. If your budget is tight and you already have a laser source, you may only need the delivery module. Evaluate whether you need the source or just the delivery path.
Product Facts
- ZMI 7724 Laser Module: The ZMI 7724 Laser Module is offered with a selectable beam size, and the currently listed SKU is configured for a 10mm beam size (SKU 8070-0351-01). If you need a 10mm beam, this is the exact configuration to order; other beam sizes may require a different SKU or custom setup.

ZMI 7724 Laser Module - ZMI 7724 Delivery Module: The ZMI 7724 Delivery Module is compatible with the ZMI 7724 Laser Module and comes in two beam size options: 6mm (standard, SKU 8070-0268-02) and 12mm (SKU 8070-0302-02). Choose the delivery module beam size that matches your optical path; the standard 6mm is the default, but 12mm may be needed for larger apertures.

ZMI 7724 Delivery Module
Which Should You Choose?
Best For
- Users building a new interferometer system who need the laser source.
- Those whose setup requires a 10mm beam and want the complete ZMI 7724 configuration.
Not For
- Users who already own a ZMI 7724 Laser Module and only need to adapt the beam size—consider the Delivery Module instead.
- Applications requiring a beam size other than 10mm from the laser module itself.
