Filmetrics Filmetrics F50 Uv Thin Film Mapper Ls Dt2 Light Source — Tested & Verified (Filmetrics)

How Much Does Filmetrics F50-UV Thin-Film Mapper + LS-DT2 Light Source | Complete System | S/N 14L093 | Tested & Verified Cost in 2026?

As of July 2026, the Filmetrics F50-UV Thin-Film Mapper with LS-DT2 Light Source (S/N 14L093) is priced at $15,900 for a tested and verified used unit. This price reflects a B-grade condition, which is typical for systems that have seen moderate use but remain fully functional. Refurbished units from trusted vendors like Ferrotec and Axus Technology typically range between $15,000 and $16,500, depending on the extent of the rebuild and included accessories. A new F50-UV system from Filmetrics can cost between $35,000 and $40,000, meaning buyers can save 40–60% by opting for a used, well-maintained unit.

The cost of failure is high: if a system is not properly tested and fails post-purchase, downtime can exceed $10,000 per day in a high-volume fab. Additionally, if the LS-DT2 light source is not calibrated correctly, it can lead to inaccurate film thickness measurements, which may result in batch rework or scrap. A unit with more than 10,000 hours of use may require more frequent maintenance, so buyers should verify the system's operational history before purchase.

Filmetrics F50-UV Thin-Film Mapper + LS-DT2 Light Source | Complete System | S/N 14L093 | Tested & Verified Specifications and Compatible Tools

The F50-UV system is a non-contact optical thickness mapper capable of measuring films down to 1 nm with a repeatability of ±0.5%. It operates in the 250–900 nm wavelength range and is commonly used with tools like the Lam Research Centura and Applied Materials Endura platforms, particularly in systems deployed between 2010 and 2015. The LS-DT2 light source provides a stable, high-intensity UV output and is typically rated for 8,000–10,000 hours of operation.

However, this system is not compatible with newer tools that require a Filmetrics F50-IR model, such as those using the ASML NXT:1700 platform. Using an incompatible light source can lead to measurement errors and system instability, potentially resulting in $5,000–$10,000 in corrective costs. Always verify the tool’s interface and power requirements before installation. The system is approximately 12 years old and should be inspected for wear on the optical bench and light source housing.

What to Check Before Buying a Used Filmetrics F50-UV Thin-Film Mapper + LS-DT2 Light Source | Complete System | S/N 14L093 | Tested & Verified in 2026

1. Verify the Light Source Hours: The LS-DT2 should have less than 8,000 hours of use. Units with more than 9,000 hours are at high risk of premature failure and may require a $2,500–$4,000 replacement.

2. Perform a Laser Interferometry Test: This test confirms the system’s optical alignment and stability. A misaligned system can lead to measurement errors and process deviations.

3. Check the UV Output Spectrum: Use a spectrometer to validate the UV output. A deviation of more than 5% from the baseline spectrum may indicate a failing lamp or degraded optics.

4. Review the System Log: Look for recurring errors, especially in the laser shutter or sensor modules. A system with more than 3 shutter failures in the last 12 months is a red flag.

5. Reject if the System is Pre-2012: Units produced before 2012 often lack the updated firmware needed for compatibility with modern process control systems. Installing such a unit can lead to $7,000+ in integration costs.

Failure to follow these steps can result in a non-functional system or inaccurate measurements, both of which can cost between $10,000 and $20,000 in lost production and rework.

FAQ

Q: Can I use the F50-UV with a Filmetrics LS-IR light source instead of the LS-DT2?
A: No. The F50-UV is designed specifically for the LS-DT2 UV light source. Using an LS-IR infrared source will cause the system to fail during calibration, resulting in a $3,000–$5,000 repair.

Q: Should I buy a used F50-UV system with more than 10,000 hours on the light source?
A: No. Light sources beyond 10,000 hours are likely to fail within 6–12 months, and replacement costs can exceed $4,000. Always check the hours before purchase.

Q: How long can I expect the LS-DT2 light source to last after installation?
A: With proper maintenance, the LS-DT2 should last 8,000–10,000 hours. After that, performance degrades, and replacement is necessary.

Q: How does the F50-UV compare to the F50-IR in terms of accuracy?
A: The F50-UV offers better accuracy for thin films under 100 nm, with a typical error margin of ±0.5%. The F50-IR is better for thicker films but has a margin of ±1.2% in the same range.

Q: Is it worth buying a used F50-UV system in 2026?
A: Yes, if the unit is tested and under 10,000 hours. You can save 40–60% compared to a new unit, and with proper maintenance, it can last another 5–7 years in production.
