SFXC Liquid Crystal Sheet R&D Evaluation Pack – 7 Calibrated Temperature Ranges

Seven individually calibrated liquid crystal sheets for precise thermal evaluation.

The SFXC Liquid Crystal Sheet R&D Evaluation Pack is a high‑performance, professional‑grade reference set of precision temperature‑sensitive liquid crystal sheets, covering seven calibrated temperature ranges with defined bandwidths.

Designed for laboratory testing, product development, and thermal analysis, this pack delivers consistent, repeatable performance where accurate interpretation of colour response is critical. Unlike decorative or craft‑grade liquid crystal sheets, each sheet in this pack is manufactured to defined calibration tolerances and supplied with known Colour Play parameters, including measured bandwidth.

These sheets are intended for engineers, researchers, and developers who require reliable, interpretable thermal visualisation performance rather than approximate or visually estimated temperature indication.

What’s included

  • Seven performance‑calibrated liquid crystal sheets
  • Distinct temperature ranges covering 20–45 °C (68–113 °F)
  • A mix of standard and narrow bandwidth sheets (1 °C to 5 °C bandwidth) for comparative evaluation
  • Non‑adhesive sheets suitable for temporary placement, testing, and evaluation
  • Manufactured for repeatable colour response in R&D and validation environments

Temperature ranges & bandwidths included

  • 20–25 °C (68–77 °F) — 5 °C bandwidth
  • 25–30 °C (77–86 °F) — 5 °C bandwidth
  • 29–33 °C (84–91 °F) — 4 °C bandwidth
  • 30–35 °C (86–95 °F) — 5 °C bandwidth
  • 35–36 °C (95–97 °F) — 1 °C narrow bandwidth
  • 35–40 °C (95–104 °F) — 5 °C bandwidth
  • 40–45 °C (104–113 °F) — 5 °C bandwidth

Including both standard and narrow bandwidth sheets allows users to evaluate resolution, sensitivity, and performance trade‑offs before selecting a final specification for production or volume use.

Key performance features

  • High‑performance liquid crystal material — not craft or novelty sheets
  • Defined colour response using calibrated Colour Play values
  • Known bandwidth enables accurate interpretation of thermal gradients
  • Repeatable performance suitable for comparative testing and validation
  • Ideal for selecting the correct temperature range and bandwidth prior to committing to individual sheets or volume orders

Each sheet is specified using calibrated Colour Play parameters (Red Start, Green Start, Blue Start, Clearing Point, and bandwidth), enabling precise interpretation of colour response rather than reliance on nominal or visually estimated temperatures.

Colour Play Red Start RS (°C) Green Start GS (°C) Blue Start BS (°C) Clearing Point CP (°C) Bandwidth W (°C)
20–25 °C 20.0 21.5 23.0 25.0 5 °C
25–30 °C 25.0 26.5 28.0 30.0 5 °C
29–33 °C 29.0 30.0 32.0 33.0 4 °C
30–35 °C 30.0 31.5 33.0 35.0 5 °C
35–36 °C 35.0 35.3 35.6 36.0 1 °C
35–40 °C 35.0 36.5 38.0 40.0 5 °C
40–45 °C 40.0 41.5 43.0 45.0 5 °C

This table defines the calibrated colour response of each sheet, allowing users to interpret colour changes based on measured start points and bandwidth rather than approximate or visually estimated temperatures.

Availability & supply

  • This evaluation pack is supplied as a mixed‑range performance reference set
  • Individual temperature ranges and bandwidths are available separately
  • Adhesive‑backed versions are available for production use
  • Suitable specifications can be supplied in volume following evaluation
  • Please contact us for production quantities, custom ranges, or technical guidance

Important notes

  • This pack is intended for evaluation and testing purposes
  • Sheets are supplied without adhesive backing
  • Colour response is influenced by surface condition, lighting, and viewing angle
