Standard borescopes cannot detect biofilm on tube walls. Not because the cameras are inadequate — because the illumination geometry is wrong. Aerodetex was founded to fix that. One probe. Three wavelengths. The wall, finally visible.
Mission
"To make biofilm in aerospace plumbing systems visible before it becomes a failure — using the physics of autofluorescence, the geometry of side-view optics, and the discipline of mission-critical engineering."
Origin Story
Working in the medical endoscopy field, the founding team at VSNDT documents a consistent failure pattern: high-resolution cameras and rigorous reprocessing protocols are not preventing microbial contamination on endoscope channels. The contamination is invisible to white-light inspection — not because the cameras are inadequate, but because the illumination geometry is wrong. The light hits the channel wall at near-parallel incidence. Surface biofilm is invisible by physics, not by resolution.
The team validates that bacterial biofilm contains endogenous fluorophores — NADH, flavins, and porphyrins — that emit in the blue-green range when excited at 405 nm. Clean metal and polymer surfaces do not fluoresce at this wavelength. The contrast is categorical, not gradual. Biofilm glows. Clean surfaces do not. The detection principle is grounded in three peer-reviewed studies and validated on clinical endoscope channels.
The medical-grade Tri-Spectrum borescope platform launches under the Endodetex brand. The VS-P probe — 1.8 mm diameter, side-view optics, three illumination channels — enters clinical use in hospital sterile processing departments. The detection principle works. Contamination that passed every standard reprocessing verification protocol is now visible in real time.
Aerospace maintenance engineers begin contacting Endodetex. The question is always the same: can this work in a fuel tank? In a propellant line? In a spacecraft water recovery loop? The geometry problem they are describing is identical to the endoscope channel problem. The same physics. The same invisible contamination. The same catastrophic failure mode — except in aerospace, the consequence is not a hospital-acquired infection. It is a mission-critical failure.
The founding team launches Aerodetex as a dedicated aerospace division, adapting the VS-P Tri-Spectrum platform for aerospace-grade environments: IP67 rating, extended temperature range (-20°C to +70°C), 3.9 mm lead probe diameter optimized for standard aerospace access ports, and a 15-day delivery cycle designed to integrate into existing MRO program timelines. The geometry gap that the medical field spent a decade documenting is now addressable in aerospace.
The Problem We Solve
Direct-view borescopes fail to detect wall-surface biofilm for three compounding reasons — none of which are fixable by upgrading the camera resolution.
Light hits the tube wall at near-parallel (grazing) incidence. Specular reflection washes out surface features. Biofilm is optically transparent under these conditions regardless of how good the camera is.
Direct-view optics are optimized for axial features — what is in front of the probe. The tube wall is at the periphery of the field of view, undersampled and geometrically distorted.
Borescope optics are focused for the center of the tube. The wall surface is at a different working distance, outside the depth of field, and out of focus even when the illumination angle is corrected.
The Solution
The VS-P Tri-Spectrum probe rotates the optical axis 90 degrees — placing the tube wall at the center of the field of view, at the optimal working distance, with illumination at oblique incidence. This single change makes the wall inspectable for the first time.
The three illumination channels — white light, 365 nm UV, and 405 nm UV — are selected for specific detection tasks. White light for mechanical defect inspection per ASTM E1417. 365 nm for broad-spectrum fluorescence screening. 405 nm for biofilm-specific autofluorescence detection, exploiting the NADH and flavin fluorophores present in all bacterial biofilm.

How We Work
Every product decision, every design choice, every technical specification is evaluated against one question: does this help an engineer see something they could not see before? Visibility is not a feature. It is the mission.
The 405 nm detection principle is grounded in peer-reviewed science, not marketing claims. We cite our sources. We acknowledge the gaps in the evidence base. We are actively working to close those gaps through research collaborations. When we do not know something, we say so.
Aerospace maintenance is not a context where "good enough" is acceptable. Every specification we publish — IP67, -20°C to +70°C, 120° field of view, 15-day delivery — is a commitment, not an estimate. We build to the standard the industry requires, not the standard that is easiest to meet.
The geometry gap is not a fundamental limit of physics — it is a consequence of using the wrong tool for the wrong problem. Direct-view borescopes were designed for mechanical defect inspection. Biofilm detection requires side-view optics and the right illumination wavelength. The solution exists. Deploying it is an engineering and adoption problem, not a research problem.
The Platform Ecosystem
The VS-P Tri-Spectrum platform was validated in medical endoscopy, scaled to industrial inspection, and adapted for aerospace. Aerodetex is the aerospace expression of a technology that has been in clinical and industrial use for years.
Medical-grade endoscope inspection platform — the origin of the VS-P Tri-Spectrum technology. The 1.8 mm probe and 405 nm detection methodology were validated in clinical settings before aerospace adaptation.
Industrial and commercial inspection platform — the VS-P probe system adapted for industrial plumbing, water treatment, and commercial aviation maintenance. Shares the same Tri-Spectrum hardware platform as Aerodetex.
The parent technology company — develops and manufactures the VS-P probe platform, Tri-Spectrum illumination system, and display unit hardware. All Aerodetex instruments are manufactured and quality-assured by VSNDT.
New Mexico
Aerodetex operates from New Mexico — home to Spaceport America, Kirtland Air Force Base, White Sands Missile Range, and the Sandia and Los Alamos national laboratories. The state's aerospace and defense ecosystem is not a coincidence; it is a concentration of the programs, institutions, and engineering talent that Aerodetex was built to serve. We are positioned at the center of the national space industrial base, and we intend to stay there.
Vision
No aerospace jurisdiction currently mandates UV fluorescence borescope inspection for biofilm detection. No standard specifies the illumination wavelength, the probe geometry, or the detection threshold. That gap will close — the same way it closed in medical endoscopy, driven by peer-reviewed evidence and documented failures. Aerodetex intends to be the instrument and the institution that defines what that standard requires when it arrives.
