Optical Axis Adjustment Jig for Laser Module Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Raman spectrometers, optical axis adjustments for laser light are necessary when the laser light source is replaced, which requires on-site adjustments of multiple optical components, disrupting the spectrometer's operation and potentially restricting access due to the need for a dedicated area.
Innovation Solution
An optical axis adjustment method and jig that allow for the adjustment of laser modules outside the spectrometer, using an optical axis adjustment mechanism to align the laser modules on a jig before reattaching them, eliminating the need for on-site adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical axis adjustment is performed on site after laser light source replacement, then the laser module can be properly aligned, but the Raman spectrometer cannot be used during the work and access may be restricted
Solution Approach 1:
The patent applies preliminary action by performing optical axis adjustment before laser light source replacement. The adjustment mechanism pre-adjusts the optical axis of the laser module in advance, so that when the laser light source is replaced, the optical axis is already aligned and no on-site adjustment is needed. This eliminates spectrometer downtime while ensuring proper alignment.
2Reliability
If multiple optical members are adjusted for optical axis alignment, then the laser light path can be properly aligned, but the adjustment process becomes complex and requires specialized procedures
Solution Approach 1:
The patent merges the adjustment of multiple optical members into a single integrated adjustment mechanism. Instead of adjusting mirrors, lenses, and other optical components separately, the invention provides a unified adjustment structure that simultaneously aligns the entire optical path, greatly simplifying the adjustment process while ensuring proper alignment.
3Reliability
If on-site optical axis adjustment is performed, then the laser module can be aligned, but the work must be performed in a dedicated laser management area with access restrictions
Solution Approach 1:
The patent applies preliminary action by completing the optical axis adjustment before the laser module is installed in the spectrometer. This allows the adjustment to be performed in advance in a controlled environment, eliminating the need for on-site adjustment in restricted laser management areas. The pre-adjusted module can then be easily installed without requiring specialized access conditions.

AI summary
In a jig mounting step (Step S1), a laser module having an optical axis adjustment mechanism is mounted on an optical axis adjustment jig in a state where the laser module is detached from a Raman spectrometer. In an optical axis adjusting step (Step S2), an optical axis of a laser module mounted on the optical axis adjustment jig is adjusted using the optical axis adjustment mechanism of the laser module. In a device attaching step (Step S4), a laser module whose optical axis has been adjusted by the optical axis adjusting step is attached to an attachment position of a Raman spectrometer.
