Why is PRISMA maintenance different?
"We don't just perform maintenance. We apply engineering to restore performance, preserve reliability, and recover the precision of high-tech equipment."
Maintaining high-precision equipment requires much more than simply replacing components. It demands applied engineering , technical diagnostics , and specialized knowledge to identify the root cause of failures and preserve the original performance of the systems.
At PRISMA Engenharia & Performance, every intervention is carried out with methodology, precision, and a focus on operational reliability, contributing to greater availability, lifespan, and safety of equipment.
The following examples show how often imperceptible details make a difference in performance and the quality of results.
01
Optical Alignment
The performance of optical equipment depends on the precise alignment of its components. Even small deviations can compromise image quality and examination accuracy.
PRISMA performs specialized optical alignment , restoring ideal operating conditions to ensure maximum precision , reliability , and performance .

Our commitment is to offer solutions that increase reliability, reduce downtime, and help your equipment operate at maximum efficiency throughout its entire lifecycle.
Calibração e Verificação Técnica
A PRISMA não realiza calibração metrológica acreditada pela RBC. Nossos serviços são direcionados à manutenção preventiva, verificação de desempenho e ajustes técnicos dos equipamentos, conforme especificações e procedimentos do fabricante.
A RDC 509/2021 não estabelece, de forma geral, a obrigatoriedade de calibração por laboratório acreditado RBC para equipamentos oftalmológicos. Quando aplicável, orientamos o cliente quanto à necessidade de calibração metrológica específica e à rastreabilidade adequada.
