Lens Cleaning Solution Efficiency on Optical Survey Accuracy among Fourth-Year Geodetic Engineering Students at Batangas State University- Alangilan

Abstract

The study examines the limitations of current practices in maintaining and ensuring the optimal condition of surveying instruments, with a particular focus on lens cleanliness and its impact on measurement accuracy. It aims to understand these limitations and evaluate the effectiveness of informative infographics as a proposed tool for improving lens maintenance, accuracy, and efficiency in surveying tasks. The use of a quantitative research approach with a descriptive-developmental design allowed for a thorough analysis of the current shortcomings in instrument care and the potential of infographic-based guidance to address these issues. Conducted at Batangas State University – The National Engineering University - Alangilan, the research involved geodetic engineering students with firsthand experience in field surveying, using purposive-convenience sampling with 50 respondents. A researcher-developed questionnaire, divided into sections covering experience in lens maintenance, assessment of infographic effectiveness, benefits, and challenges in application, was used for data collection. Statistical tools, such as the mean and composite mean, aided in data analysis, enabling a quantitative assessment of the respondents’ perceptions. The key findings highlighted concerns about improper lens care potentially affecting survey accuracy, while also emphasizing the positive reception of the infographic tool, which was praised for its clarity, ease of use, adaptability, and applicability in both laboratory and field settings. However, some challenges were noted, such as respondents’ initial unfamiliarity with proper procedures and the need for additional training to maximize the infographic’s effectiveness. Overall, the infographic has emerged as an innovative tool aimed at improving lens maintenance practices, enhancing survey accuracy, and fostering responsible instrument handling. This study contributes to the advancement of geodetic engineering education and practice by systematically evaluating an effective approach to address current gaps in optical survey instrument care.

Introduction

The text emphasizes the importance of optical lenses in engineering applications, particularly in geodetic surveying, where measurement accuracy heavily depends on proper lens condition and maintenance. Lens contamination from dust, fingerprints, moisture, and environmental exposure can obstruct light transmission, cause optical aberrations, and reduce survey accuracy. Although advancements in lens manufacturing and cleaning solutions have improved optical performance and extended instrument lifespan, inconsistent maintenance practices persist among engineering students despite international and national guidelines.

The study highlights that using appropriate optical cleaning solutions can significantly improve lens clarity, optical transmittance, and measurement reliability, while improper cleaning products may damage lens coatings and reduce performance. Environmental factors such as humidity and temperature variations continue to affect survey precision, reinforcing the need for effective lens care.

Focusing on fourth-year Geodetic Engineering students at Batangas State University, the research aims to evaluate the effectiveness of various lens cleaning solutions on optical survey accuracy and assess current cleaning practices, student perceptions, and the usefulness of an instructional infographic. A descriptive developmental research design was employed, using researcher-made questionnaires distributed electronically to 96 students.

Results indicate that students generally practice proper maintenance and strongly agree on the importance of regular cleaning and inspection of instruments. They also perceive lens cleaning solutions as effective in improving optical clarity and supporting measurement accuracy. However, findings suggest a need for enhanced training and standardized maintenance practices to ensure consistent application of proper cleaning methods.

Conclusion

Based on the findings of the study, the following conclusions were drawn: 1) Respondents’ surveying experiences highlight the essential role of proper lens care in ensuring accurate and reliable measurement results. 2) The informative infographics were viewed as effective tools for improving understanding of lens cleaning procedures, enhancing optical clarity, and supporting accurate survey work. 3) Respondents recognized the infographics as valuable resources that promote efficiency, reinforce correct maintenance practices, and contribute to improved surveying performance. 4) No significant barriers were identified in implementing the infographic tool, as respondents showed strong willingness to use it due to its clarity, relevance, and practicality. 5) The use of informative infographics ultimately enhances lens maintenance knowledge, reduces errors related to improper cleaning, and supports more precise and sustainable surveying practices.
