The new production line integrates:
Precision optical alignment to maintain consistent optical pathlengths for absorbance and fluorescence detection.
Advanced bonding techniques compatible with both optical glass and biocompatible polymers.
Microfluidic flow channel machining and sealing, ensuring repeatable fluid dynamics and minimal cross-contamination.
Quality control and interferometric verification of optical surfaces to meet biomedical signal integrity standards.
These flow cell assemblies serve as the optical interface for the Beckman Coulter portable HIV detection module, supporting the device’s ability to detect and quantify HIV biomarkers in low-volume biological samples.
Enabling Portable Biomedical Diagnostics
The integration of Tower Optical’s optical manufacturing precision with Beckman Coulter’s biomedical design expertise exemplifies a multidisciplinary approach to diagnostic device engineering. The resulting module combines miniaturized optics, efficient light coupling, and controlled fluidic handling to enable field-deployable, rapid HIV testing.
Key design considerations include:
Optical throughput efficiency to ensure reliable detection at low analyte concentrations.
Compact system integration to reduce power consumption and device footprint.
Temperature and environmental stability across diverse deployment conditions.
Outlook
With this expansion, Tower Optical enters a new domain at the intersection of optics, microfluidics, and biomedical engineering. The company’s capability to deliver complete optical subsystems positions it as a valuable partner for diagnostic instrument manufacturers developing portable, high-sensitivity analytical devices.
Tower’s long-term goal is to establish a dedicated life science manufacturing line, incorporating cleanroom assembly, surface functionalization, and optical testing protocols tailored for biomedical applications.
