CCD Interface Flange for Omni-λ Series Spectrometers

Overview

The CCD Interface Flange is a precision-machined mechanical adapter designed exclusively for seamless integration between ZOLIX Omni-λ series monochromators/spectrometers and industry-standard scientific CCD detectors. Engineered to maintain strict optical alignment and mechanical stability, this flange ensures minimal vignetting, repeatable detector positioning, and consistent focal plane registration—critical parameters for quantitative spectroscopic measurements. It operates on the principle of standardized mechanical interfacing rather than active signal transmission; its function is purely passive, enabling reliable coupling without introducing optical aberrations or thermal drift. The flange conforms to common detector mounting conventions—including C-mount, F-mount, and custom sensor-specific configurations—while preserving the native back-focal distance required by Omni-λ optical designs. Its use is essential in applications demanding high signal-to-noise ratio, spectral reproducibility, and long-term system calibration stability.

Key Features

• Precision CNC-machined aluminum alloy construction with black anodized finish for dimensional stability and corrosion resistance
• Optimized thickness and bore geometry to maintain OEM-specified back focal length (BFL) tolerance within ±0.05 mm
• Integrated kinematic mounting features including three-point contact alignment pins and tapped M4 threaded holes for secure, repeatable CCD attachment
• Compatible with vacuum-compatible and cooled CCD assemblies (e.g., Andor iDus, Princeton Instruments PIXIS, Hamamatsu C11090 series)
• Designed to withstand thermal cycling between –30 °C and +60 °C without loss of mechanical integrity or alignment fidelity

Sample Compatibility & Compliance

This interface flange supports direct mechanical coupling to all generations of ZOLIX Omni-λ spectrometers (including Omni-λ150, Omni-λ300, Omni-λ500, and Omni-λ750 models) and is validated for use with front-illuminated and back-illuminated CCD sensors up to 26.6 mm diagonal format. It does not alter spectral response or introduce measurable stray light under standard laboratory illumination conditions (ISO 14644-1 Class 8 cleanroom ambient). While the flange itself carries no electrical certification, its mechanical design complies with ISO 2768-mK general tolerances and aligns with ZOLIX’s internal mechanical interface specification ZS-IF-CCD-2023. No regulatory certification (e.g., CE, UL) applies, as it is a passive optomechanical component exempt from electromagnetic compatibility or safety directives.

Software & Data Management

As a purely mechanical interface, the CCD Interface Flange requires no firmware, drivers, or software configuration. It introduces no data latency, signal degradation, or metadata dependencies. When used with ZOLIX’s OmniDriver SDK or third-party acquisition platforms (e.g., LabVIEW, Python-based PyVISA + Andor Solis API), spectral data integrity remains fully preserved—no additional calibration steps beyond standard wavelength and intensity calibration are introduced by the flange. Audit trails and instrument logs generated during GLP/GMP-compliant spectroscopic workflows remain unaffected, satisfying traceability requirements under FDA 21 CFR Part 11 when paired with compliant host systems.

Applications

• Raman spectroscopy setups requiring precise pixel-to-wavelength mapping consistency across multiple acquisitions
• Fluorescence lifetime imaging (FLIM) and time-resolved photoluminescence where detector registration repeatability impacts decay curve fitting accuracy
• UV-Vis-NIR absorbance quantification in pharmaceutical QC labs operating under USP and ICH Q2(R2) validation guidelines
• Plasma emission monitoring in semiconductor process tools, where long-term spectral centroid stability is critical
• Custom multi-channel spectral detection arrays integrating multiple CCDs on a single Omni-λ output port

FAQ

Is this flange compatible with non-ZOLIX spectrometers?
No—it is dimensionally optimized for the Omni-λ series’ exit port mechanical interface and back focal distance; adaptation to other spectrometer brands requires custom machining.
Does the flange include sealing O-rings for vacuum applications?
Standard delivery includes no O-rings; vacuum-compatible versions with Viton gaskets and CF-35 flange variants are available upon engineering consultation.
Can I use this flange with CMOS sensors such as sCMOS cameras?
Yes, provided the camera housing conforms to C-mount or F-mount standards and the sensor’s active area fits within the flange’s clear aperture; mechanical fit verification is recommended prior to integration.
What is the maximum allowable torque for mounting screws?
Maximum recommended tightening torque is 0.45 N·m per M4 screw to prevent thread deformation or flange warping.
Is technical documentation (e.g., STEP files, GD&T drawings) available?
Yes—dimensional drawings, material certifications, and RoHS compliance statements are supplied with OEM orders under NDA.
