Multi-sectioned Window for Spectroscopic Cyclic Error Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectroscopic devices face challenges in reducing cyclic errors due to the addition of beam splitters and mirrors, which increase costs and introduce optical surfaces that contribute to cyclic errors.
Innovation Solution
The design incorporates a multi-sectioned window with a top side featuring a beam splitter section and an anti-reflective (AR) coated section, and a bottom side with an AR coating, allowing for beam splitting and transmittance while minimizing cyclic errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam splitters and mirrors are added to create reference channels, then cyclic error reduction is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the beam splitter and window into a single integrated multi-sectioned window component. The beam splitter functionality is incorporated directly into the window structure through different coated sections, eliminating the need for separate beam splitter and mirror components while maintaining the reference channel functionality for cyclic error reduction.
Solution Approach 2:
The multi-sectioned window serves multiple functions simultaneously: it acts as a protective window, a beam splitter, and a reference channel director. Different sections of the window have different optical coatings (AR coating, beam splitter coating) that enable various optical paths to be created within a single component, reducing the overall number of parts needed in the system.

AI summary
The present disclosure includes an optical head for a spectroscopic device configured to produce a beam of light, a reference signal detector, and a signal detector. A mirror reflects the beam of light from the light source toward a multi-sectioned window having a top side and a bottom side. The bottom side includes an AR coating and the top side has a first section including an AR coating and a second section including a beam splitter with transmittance and reflectance. A first beam path for the beam of light is defined by the mirror, the second section of the multi-sectioned window, and the reference signal detector. A second beam path for the beam of light is defined by the mirror, the second section of the multi-sectioned window, a medium contained in the spectroscopic device, an additional mirror, the first section of the multi-sectioned window, and the signal detector.
