Now through December 31, 2023, get 15% off when you buy 2 or more packs of OLTESPA-R3 visible-tip probes!*
Use promo code FALL23 during checkout.

The OLTESPA-R3 is a visible apex tip. Just point the free end of the cantilever at the sample feature of interest when in the navigation GUI of your AFM and hit engage.

The tip located directly beneath the cantilever apex will land in the perfect position for scanning every time!

The probe also features a tetrahedral sharpened tip with a 7nm tip radius for crisp topographic images.
A 70khz resonant frequency and 2N/m spring constant make this probe perfect for gentle imaging of samples in tapping mode whilst maintaining tip sharpness.

Suitable for a wide range of polymeric, metallic, semiconductor, ceramic and similar samples.


*Promotion valid thru December 31, 2023. US customers only. Shipping charges are not discounted. Promotion cannot be combined with other promotions or bulk discount rates.
