Off the shelf (OTS) homogeneous phantoms

Our Off-the-Shelf (OTS) Homogeneous Phantoms are high-quality, non-customizable optical phantoms made from the same advanced material used in our multi-layer phantom line. These phantoms are ready to ship within 1–2 weeks from payment, offering a rapid and cost-effective solution for optical system testing and calibration.

Each phantom is a unique, pre-manufactured piece, with specific shape, size, and optical properties (absorption and reduced scattering coefficients) at predefined wavelengths. The available inventory varies over time.

We invite interested users to contact us directly to receive the current catalog, which will include phantom code, geometry, measured optical properties (at least two wavelengths), and pricing.

For selected thicker models (typically ~4 cm), we also offer extended wavelength characterization (480–1650 nm) as additional service.

🚫 Not suitable for MRI, X-ray, or CT imaging applications.

Key Features & Benefits

• ✔ Ready-to-Ship in 1–2 Weeks
  Skip production queues — ideal for time-sensitive research and device testing.

• ✔ High-Quality Optical Standards
  Manufactured with the same material and precision processes used in our premium custom and multi-layer phantoms.

• ✔ Traceable Optical Properties
  Each phantom includes absorption and reduced scattering coefficients at a minimum of two wavelengths — measured and documented.

• ✔ Affordable, Entry-Level Access
  The most budget-friendly option in our product line, ideal for constrained projects or early-stage prototype validation.

• ✔ Perfect Inter-Layer Adherence
  When stacked, multiple phantoms adhere without air gaps — allowing users to simulate layered structures with high fidelity.

• ✔ Eligible for Extended Characterization
  For thicker phantoms, optical property measurements across an extended wavelength range (480–1650 nm) are available on request.

• ✔ Durable & Reusable
  Though economically priced, all phantoms are robust, stable, and suitable for long-term use — a true long-life investment.

Why Choose off-the-shelf homogeneous phantoms?

• 💰 Cost-effective without compromise
  If customization is not essential, our off-the-shelf phantoms offer the same scientific-grade quality at significantly lower prices.

• 🚀 Fast delivery
  For urgent timelines, these phantoms are your fastest option — no need to wait weeks for a made-to-order model.

• 🧪 Great for beginners in Biophotonics
  Ideal for users who are exploring phantom-based validation for the first time, or who are unsure of the exact parameters they need. These phantoms help you learn what works without a big initial investment.

• 🔧 Build your own multi-layer structure
  Combine different thicknesses and shapes from our off-the-shelf selection to create cost-efficient, physically accurate multi-layer setups.

• 🧭 Start simple, then go custom
  Many of our customers begin with OTS phantoms and, after gaining experience, progress to fully tailored designs as their technical needs become clearer.

Applications

These phantoms are suitable for all the main applications of our General Homogeneous Phantoms, including:

🔬 Calibration of optical instruments (TD, FD, CW NIRS)
Validate the performance of TD, FD, and CW NIRS systems using stable, tissue-mimicking optical standards.

📊 Device comparison studies
Standardize measurements when comparing the behavior of multiple optical devices or probe configurations.

🧠 fNIRS probe validation
Assess sensor placement, signal quality, and repeatability of functional near-infrared spectroscopy setups.

💡 Light propagation & simulation model testing
Benchmark the output of photon transport models using real-world physical phantoms with known properties.

🛠 Prototype development & quality control
Support rapid device prototyping and ensure manufacturing consistency with reproducible test conditions.

📚 Training & educational use
Provide a hands-on, risk-free environment to train students, engineers, or clinicians on optical system usage.

Multi-layer structure feature

➡️ When multiple OTS phantoms are stacked to form a multilayer structure, their applications extend to those of our Multi-Layer Phantoms, such as:

🧪 Depth sensitivity & layer discrimination studies
Evaluate how well your system can detect changes at different tissue depths in stacked phantom layers.

🎯 Algorithm validation for complex tissue structures
Test and refine imaging algorithms under controlled, layered optical conditions without investing in custom builds.
